I have a pretty medium project
I use project folder format, because most of the game logic is written in TypeScript and compiled into one ~2 mb js file included in the project, so I don't have much script files or events in the project. Total size of the project is literally 10 mb!!!
And the saving can take from 5 second, to full 2 minutes, and also my PC can fully freeze for 10-20 seconds in the process. I just can't imagine what can you do for 2 minutes with the 10 mb project, and especially to make PC freeze as hell. And also it doesn't matter what changes I make. I can make like 30 changes to the scene, and saving will take 10 seconds. And the same time, I can edit one action in event sheet, and the saving will take 1 full minute.
I use latest stable C3 version, and latest stable chrome versions. Chrome extensions doesn't affect that at all, I checked multiple times. Also, i have a pretty big layout. Probably this is the problem?
