I've got prefabs/gameobjects in the scene with missing scripts... only when I try to remove these components soon as I click remove the editor crashes.. seems this issue has been around for a years looking into it. No script errors, can even play test the game without issue, only the disabled and missing components cannot be removed, and I try delete any of these gameobjects from the scene hierarchy it also causes the editor to crash. 5.5.0f1 (yeh I'll get around to sending a bug report) I tried putting these same prefabs(without scripts) into another project and removing the missing script components.. and it worked fine no crashes. The reported bug I had before has now disappeared and is not an issue and yet I'm left with a new project with scene/prefabs that will break the editor if I try clean up the missing scripts.. but the reported bug with https://forum.unity3d.com/threads/c...-in-text-file-projectsettings-5-5-0f1.442596/ no longer happens for me now. Anyway Unity really should have some better project management tools in place.. things like finding missing scripts that are on components, short of actually looking at all prefabs/gameobjects yourself, its all bit naff really. Yeh I've seen a few scripts laying about the internet unity answer hub that attempt a solution to detect and remove, can we not get professional on this, the console logs script errors but components with missing scripts.. that's just eh left out, not even warning message on them? Then the case of wanting to reduce project size, programs like maya/afterfx etc etc and others have had project archiving feature for years now, and it helps alot... yeh its more complicated here with scripts and how developers may have there own custom way of using assets that editor might not detect, but even something that gets 99% of the job done in reducing the amount of files in the project that are not used or referenced in the scene, prefabs, scripts that the editor can detect being needed...its kinda practically already done when building for a platform.. sure would help when it comes to sending in a bug report...and project spring cleaning.. yknow because downloading assets from the store can be a mess for projects with certain ways authors package there stuff.. and it doesn't help that unity doesn't really have a plugin system that contains this stuff better when you want to uninstall a package. ie 2 packages that use standard assets for example.. you keep one but if you remove the folder they both dumped there stuff into..yknow its just a mess. this stuff should be improved on at the core/editor design, not further store assets that attempt to try provide a solution ... install the package uninstall package to manage uninstalling other packages... and it its still mess. And I'm still annoyed that you have not come up with a decent solution for "Missing Script", can we not a human readable record of the said missing scripts actual filename or something here, i don't even care if its stored in some completely different project setting file and not in the meta. Supposedly some solution to this was attempted but shot down for some reason i think it was mentioned at one of unite events, the reason made sense.. what didn't make sense is why it got left without a workable solution again!
