Maybe AI can't calculate distance from towers? Stacktrace:

Very strange, it's working for me. How can pushing a -1 to vector can crash? Something wrong must have happened before, probably out-of-range write to one of the neighbouring arrays. [It'd be good to replace them with vectors.]

Please check if r2556 fixes the issue.

No crash. Fixed I suppose.
