Today I decided to give sandbox mode a go, just for the old Warlock 1 feel. Things were going great on challenging difficulty until about turn 110-120 when ALL of the other rival mages began to cast the unity spell at the same time. Now the problem with this is that these other mages were far behind me in research, and did not have anywhere near the 5000 mana to even begin casting the spell as far as what the trade screen claimed their current mana and research to be. When the first mage began casting, I made swift movements to try to eliminate him (which I was within means to do, so the bug wasn't going to be game-ending) but within 5 turns, 4 new rival mages began to cast unity. Please fix this bug to make sandbox playable!
