I want to start off this post by saying I'm brand new to Panzer Corps and I've really been enjoying this game. The editor is great and I've been making a bunch of Coop scenarios for me and some friends to play. I've run into one issue though I haven't been able to solve. Briefings only show up for whoever is playing player 1, every other player goes directly to deployment. Testing the scenario in singleplayer works as intended. The briefing will appear for each player slot before they enter the deployment phase, however this will not happen in multiplayer. I've attached a couple examples if anyone would like to look at the scenarios or reproduce this issue.
