During a tournament match with the in-combat display active if the player uses the main menu (via escape) the following error spams repeatedly.
At mission template mst_tpe_tournament_standard trigger no: 10 consequences. SCRIPT ERROR ON OPCODE 920:Invalid Overlay ID:12 LINE NO: 16:
What you're seeing is the game trying to update the match timer, but since the combat display is down, as it always goes away after changing screens, it is throwing a fit.
This issue has been corrected with TPE version 1.5
