I don't really remember it being this way in Trinity (and tbh, I can't be arsed to check 'cause I don't have any saves on this computer.) Anyway, I've noticed that after researching the improved phasespace destabilization for the TEC Starbase (either faction), the player's tooltip on the passive lists that it removes 50% antimatter, and 25% hull points on a jump, but under it, it lists them both again, but this time at 100% antimatter, and 50% hull points. On hostile ships, it sums them so it says you lose 150% Antimatter and 75% Hull for jumping away from an enemy starbase. I didn't notice losing 75% hull (Full hull points on my level 1 Rebel Titan, about 8300 or so, and it only dropped to about 5000 after jumping). Whether intentional or not, the antimatter thing is probably fixable, seems silly to remove more than 100% antimatter when it still caps at 0 remaining.
