I get the following error in the Seven Portals when activating the script to open the portal to the Guardian of Ice:
- (.GetPlanePointZ)
- TProgs::ExecuteFunction
- (ExecuteLineSpecial)
- VACS::RunScript
- VACS::Tick
- RunThinkers
- P_Ticker
- SV_Ticker
- ServerFrame
- Host_Frame
Exiting due to external exception
It seems related to the stairs building down.
