There is something terribly wrong with v144.
I had to downgrade to 143 again (which is already bad enough due to that horrible memory leak).
No OR-block in my game is working in v144 which, in my case, means that my platform character can't move at all. It's a disaster. Thank god I learned from the chaos that was v143 and made a backup of my game before trying out v144.
I really appreciate the frequent beta updates but in this case Construct 2 was completely destroyed by it. Nothing works.
