The Nuke Card Mod received an updated and got merged into the custom card package Mod. The old nuke card Mod version can still be used cause it runs as different Mod. So I suggest, if the new improved version will be used, you play a game or two with the custom card package mod and enable the nuke card.
The same ones we reported yesterday. We tested again today and the same error is happening when a player tries to join the game on the new mod (combined with the other mods that ps is using)
If I am right, it's not a bug of the mod. I think it's a bug of the reload code function combined with the mod data. Fizzer will fix it with the next update. https://www.warlight.net/MultiPlayer?GameID=13668678 works, it hasn't the other mods, but the mod works basically.
Edit: Found a missing bracked that caused the bug. It is now fixed
