Gmod crashes instantly if I remove props (Singeplayer only)

[Knas]

Hello,

I got this problem in gmod, everytime I delete a certain amount of props or a contraption in gmod, the game instantsly crashes. This happens only in singelplayer, I got a decent computer and I only got a few addons and all of them are up to date. I got no "Something is creating script error" in top left screen or something like that. The game doesn't freeze or anything, just closes. As I said this happens only in singelplayer, does anyone know why this is happening and got a solution? Please help me I am desperate.

Switch to dev version of the game. It is fixed there.

Will my addons disappear if I switch to dev version?

Obviously not. The game will be the same, just with latest [b]not fully tested[/b] changes.
