hello, I also have the same problem, the updates made after the r344.2 version caused several bugs in my ready-made games and also in the game that I've been developing since the beginning of the year. Ex: enemies patrolling and locked to the wall, traps not responding to event commands, etc. I know of another DEV who is having the same issue. Because of that I'm having to transfer the games to the stable version r344.2 and it's giving me a lot of work. I hope they fix this.
