Vassal 3.7.16.
Game opens with “ERROR: You have placed more than the allowed number of this ship type.” error message. Can’t close message or start game.Can’t even close Vassal without using Task Manager.
Using Windows 11 Desktop, fully updated.
When you say “game opens”, do you mean the module? A scenario? A saved game? A log?
This is a longstanding problem due to module design that unintentionally relied on buggy VASSAL behavior that was later fixed. The problem was isolated in January 2024 on Discord in the #tech-support channel, but perhaps the method for the fix was never relayed to the designer.
Until any of that happens, the newest version of VASSAL that will run this module without errors is 3.4.7, if memory serves.
