This is an issue with the "teddy's menu simulation" mod I believe as it started happening when I downloaded that mod, but it is an issue nonetheless
Now an important thing to know about this error is that the simulation actually does begin and works well, it catches on fire but after a while seems to explode in an error way. Now there is a small chance it could be caused by the water turret extinguisher mod but I am unable to check that at this moment

The error log is:

"The scenario level caused a non-recoverable error."
"Please report this error to the scenario author."

"Error while running event level:on_nth_tick(1)"
"LuaEntity API call when LuEntity was invalid"
"stack traceback:"
"[C]:in function'index' "
"___on-lab/menu-simulations/menu-simulation-fusion-lab.lua:34: in function<___on-lab__/menu-simulations/menu-simulations-fusion-lab.lua:26"

Alright I believe I fixed the issue by turning down the forced timer that mod adds down to 20 seconds, from my understanding it for no apperent reason forced not only it's and vanilla simulations to 60 seconds but also other modded ones leading to issue such as this mod's simulation being screwed over

Update: No it is 100% the water turret issue for some reason probably has something to do with the fire mechanics that one adds
