I am currently working on a dungeon crawler, a dungeon with 100 floors. I am currently at floor 80 and I have hit the 999 monster troop limit. Of course quite a few groups are empty, simply to get an easy way to look at the different monsters, bosses, special enemies and floors. Here is a screenshot (the game is in german):

Even if I would remove all of this free space, I am pretty sure I wouldn't get enough to add the monsters from 81-90, as I have roughly ~10 monster troops per monster. Also, I am working heavily with variables for monster troops (all enemies are visible), so I would have to redo the whole troop database if I want to continue to do so easily (unless I use more variables, which however is pretty annoying).
Please tell me there is a way. Else I may have a serious problem.
