Crash with RainBowStar.wad

[Jive]

I was playing with RainBowStar.wad, the map that I done to demonstrate the capacities of Doom Legacy, and all seemed fine.
Then I thought that the monsters were annoying for such a study and I came back to KDX (the King Elvis Launcher) to check "No monster".
I launched again the game and... CRASH!!!

I just come back to let you know that I was able to play with it without monster, and ALL was fine (no crash)!!!

Such a compatibility is simply awesome
I noticed only a small problem: the value 255 (scroll wall using sidedef offset) don't work properly (sector 74)

Works fine with 1.0.16

No!

I have now numerous crashes, and sometimes it's loaded and played finely...

Something makes me think that the first script makes it crashing.
At least, it crashes before its activation, or when it's activated, but it don't have the time to operate.

I didn't have any crash with the previous version of GZDoom.

I made ALL the changes AFTER the crashes, searching what could hang the engine. The editions didn't changed anything and it's still crashing, most of the time.

Here is the script:
