Hi @Ashley & @Tom,
I'm afraid I'm unable to replicate this error on a smaller scale.
I'm seeing the below:
It happens when the game calls a level change on a certain level, when a certain object is on the layout. I have located the line which will stop the glitch, but it doesn't seem to help me. I was able to use it perfectly fine in the previous stable version r95.
I'm afraid it goes against your request for bug reports, but my game has over 150 events, and an awful lot of objects. I've tried cutting the project down, but it keeps having the message saying that all objects need to appear on one layout. Which I'm struggling to figure out.
Seeing as I've been able to locate the line with the error, might I be able to send you the full project to have a look at, or would you rather I hack and slash the project until I get it down to a more acceptable size?
In either case, how would you like me to send it?
