Hello,
ive found an issue not specifically related to your mod but figured it'd be interesting to know, or at least to log somewhere.
If the total combination of hullmods and/or special pirate stuff make it so that you reach -100% hull (aka 0 hp), whenever you deploy the ship in combat, they just fade out and disappear and make any other deployment (friends and foes alike) impossible and therefore, hangs the battle forcing you to endcombat.
This means:
1. If a 0 hull ship is deployed at the beginning, they will disappear and "block" any subsequent deployment including the enemy initial spawn, effectively making you float inside an empty map until you force "endcombat"
2. If a 0 hull ship is deployed later during the stage of a battle, it "blocks" any enemy reinforcement/deployment but not your manual deployments. It still forces you to "endcombat" after you clean up the remaining enemies on the map though.
In particular, ive combined "internal tank -20" and "cargo carver -20" with "structural cargo retrofit -60" (which i cant remember from which mod its from) to achieve this issue.
