1.9.8 custom properies undo problem

[Kilinich]

Another annoying problem for thyme:

If I set custom variables for geom (from onLaserHit or from script menu), it's not reset/removed on undo and keep some value.

I didn't check it deep, but something wrong/changed from 1.8.5
I need time to figure it out.

You mean if you make a script that, onCollide, creates a new local variable, then when you undo SimStart, it remains what it was when it was created, not what it was when you entered the script?

This just happened to me in 1.9.7.
