[Trigger] Multiboard Issue

[The Nightmare Book]

Hello everyone! I have next issue:

• I'm working on campaign on 1.31 patch, latest before Reforged. I'm creating some sort of TD and I use multiboard to show player what enemies he could see in coming wave;
• But strangely game just crashes when it comes to multiboard changes. For example, waves from 1-4 works normally, but when it comes to showup wave 5 data, game just crashes.
• What could be wrong? I use the same triggers for all wave multiboard showing, same structure.

Screenshots here:

Why do you have that Condition and the trigger queue stuff? Seems unnecessary as far as I can tell.

Anyway, are you sure it has to do with the trigger?

Condition is from my previous bad exp;
I think yes, because I use the same triggers for all waves, and all waves from 1-4 runs normaly. But on wave 5 game just crashes. Yesterday I've encountered the same crash on wave 3, but I fixed it by changing amount of multiboard rows from 3 to 2 and removing third wave enemy type from that wave.
I don't that there I have the same variant...
