UnityWebPlayer started crashing for no apparent reason

Hi,
We have developped a set of games using Unity3d for the UnityWebPlayer.
We haven't updated the games in a few weeks.
However, since today, the WebPlayer started to crash in several PCs (different countries).

we are looking at this from 2 different perspectives:
1. what is making it crash?
2. why it started to crash without us having changed anything?

as to #1, it seems that the problem lies in the animation part.

(webplayer_win): AnimationEvent::Transfer<SafeBinaryRead>
(webplayer_win): UnityWinWebStartData
(Mono JIT code): UnityEngine.Animator:SetLookAtWeight (single,single,single,single,single)
(Mono JIT code): UnityEngine.Animator:SetLookAtWeight (single)
(Mono JIT code): Avatar:FixedUpdate ()
​

Now, the big question for us is #2.
It seems that this is related to WebPlayer being automagically updated to 4.3.
Can anyone help us understand if this is possible?

Thanks

 

Thanks god I am not alone!

We have the same thing happening!!
We have over 60 000 daily players and over 20% of them have their client crashing for the last 24h.
Like you, no update of the binary, but it looks like there was a force update of the WebPlayer that causing the crash.

We have no way to fix it, and have lost a large amount of money because a lot of our high spender can't access the game.
I am outrage.

Unity WebPlayer team, you owe us an answer!

 

Hi,
Not sure if it helps you, but we just located the cause of the crash.
It's a call to UnityEngine.Animator.SetLookAtWeight that crashes.
We are looking for a way around it.

But, like you, we just had the crash appear a 2 critical demos

Very unhappy with it.

Jus tested and, under WebPlayer 4.2.2f1 everything is fine.
Under 4.3.0f3 it crashes.

 

This happened to me on a windows stand alone build as well. 4.2.2 worked fine, but the latest build of my game in 4.3.1f1 broke the game. I'm going to try and rebuild it on 4.3.0f4 and see if I gt the same results. Will post update once I figure out if it works or not.

This was the footer in my crash log

Has anyone reported this bug?

 

Hey, Could you post the bug report number in this thread for me too?

Thanks

Dear Graham,
We found a workaround based on the computers where it did and did not happen.

Basically, the crashes happened for a single game (of 4 we used) and whenever the plugin version was 4.0.1f2.
For completeness, the webplayer version was 4.3.1f1, webdata version was 4.2.0f4 and engineversion was 4.3.1f1.

Other versions of the plugin (4.3.1f1, 4.3.4f1,4.1.2f1) never caused a crash with any of the weblayer versions (4.3.4f1,4.2.1f4).

So, we simply detect whenever the plugin is v4.0.1f2 and ask the user to update the webplayer.

If you want to, we can send a set of logfiles captured in different computers. Just let me know where to send them to.

Thanks

 

I'm getting a similar stack trace as well every time I exit my game (Win32 standalone):

I'm occasionally also getting reports of this from customers. Windows and Mac.

Bugs bugs bugs.

Unity 5 will be even worse as they cram even more features in, some of which obsolete old functionality that will then never be fixed. Note that this bug seems to first appear in the version of Unity where AnimationEvent support was added to Mechanim. I'm not even using Mechanim, but instead the "legacy" animation system, so I worry this will never be fixed.

 

Like some others, I have the animation event error as well - this one here seems to be consistent as I noticed another dev is having the same exact error as well.

(AstralTerra) : (filename not available): AnimationEvent::Transfer<SafeBinaryRead> + 0x25385a

Does anyone know if maybe it was fixed in 4.5? Been dreading downloading and upgrading as Unity has a history of adding new bugs everytime they push out an update (which I suppose might be standard but is dangerous for the team that has a game on the market that is also in dev still).

 

What is the status of this issue? Has it been fixed in a recent patch/update? I'm still on 4.3.4f1 and this issue stops my development dead in it's tracks. If it's been fixed, I guess I need to update.

Thanks.
