I'm sorry but I didn't think to save the file. It was the C4st1g4t3 4 th3 g0dh3ad module. I spawned in with a Raleigh, Deaths Head, Pegasus and Everest in a row to the right of the tree and didn't move any characters for a few rounds. As soon as enough Manticores got in range to Heatgun, the third enemy unit would use its first summon to hit my Everest and the game would freeze the exact frame the Pegasus bumped into it.
