Why does this crash?

works some games and then crashes

Because the comp being used is using units that don't have tiers (stars) so comps that include T-Hex, Apex Turret, Void Remora, Rift Herald, Baron. These comps shouldn't be used anyway since the bot doesn't have logic for them and results with units not being placed correctly since T-Hex or whatever is in the spot it wants to place an actual champion. I don't plan to add logic for these since there will be something different by next set

Just exclude comps that have non-champion units from your selection

This has been fixed the the newest update. You can use summon unit comps again
