Getting an error

[Tabris666]

Well was testing two stages library of the seers and belus but somehow it randomly crashes while loading with error in line 2177.
the code is what was included in belus and line 2177 would be this one
triggerall = (StageVar(info.name) = "Belus") || (StageVar(info.name) = "Library of the Seers");---add stage
since is a random crash kinda hard to even know what is the real issue.

this was the whole code which was copy paste

If it crashes randomly it's probably not an error in something that is always loaded. But the exact error message would be helpful.
