Gamebreaking bug for the mekara. Summoning battle sluga (via the city spell) spawns an infinite ammount of these units causing the game to crash and lock up. Additionally, and a potential balance issue, is that the spells to upgrade to sluga have no resource cost, making their world spell rather pointless. In fact the whole mechanic - being able to turn familiars to slaves to battle sluga for free, is both counterintuitive to their slave generation promotions, and seems incredibly broken, since 40 production (non military for better or worse) equates to strength 5 (rank 3 weapon limit) units. I seem to recall in an earlier iteration that familiars couldn't be upgraded to slaves, and there was a gold cost to turn slaves to sluga, and sluga to battle sluga. Is there some other restriction I'm missing? Hard to test when the game crashes upon getting the ability to create these units. As a side note I found the source of one problem with the sidar. Their racial promotion is only applied to living units and farmers aren't alive 0.o The fix is relatively simple I think. Remove the living restriction and instead deny the promotion to siege units. This doesn't fix heroes, but it's probably better to adjust their sight values instead.
