Hello everyone, you're my last hope.. So to explain my problem. For an unknowned reason, my unity started to ignore my transition link, triggers, exit time etc.. In play mode. I made a simple example: Here is what happend in play mode: https://gyazo.com/af49460b5dc5a0135072ce7ba574dd6e Here is the animator: https://gyazo.com/7f6e6409dec39305762ef6f8fb4ef4d5 Here are my parameters https://gyazo.com/f82b25708db03e345e11f927ad100315 Here is anomther example: https://wetransfer.com/downloads/9bafec2d5b5a9b2e201a3af4512c60c420200427125658/13e481 (bit longer, but ou can see some of the animations looping for no reason, loop is disable) So, to trigger the Menu In animation you've to press a button that have a trigger on click, same for the out animation. Everything worked few days ago, I didn't touch unity for like 2 days and I don't know how to solve this issue. It's clearly a local bug, because it's working fine on my friends computer (we're working with git) When I'm cliking out of the play window, it seems to work fine but.. To test my S***, I've to click in this play window so.. I tried to uninstall Unity, delete temp files, switch version, it's remains the same. The fun thing is, when I'm making a build, it's working normaly.. I tryed everything, except buying a new computer but.. well. Thank you for your time mates..
