BUG REPORT: "Merging Towers Cost Lowered" upgrade is non functional.
DETAILS: While attempting new mega tower combinations in fixed mode, I attempted to craft one using; Charge Tower 4, Fire Rate Boost 3, Damage Boost 4, and Area Burst 4. I attempted this in the level "Open Split" but the merge would have cost 1187 of my remaining 1175. I did a couple alternate levels for XP and returned after purchasing the "Merging Towers Cost Lowered" upgrade. The merge still costs 1187.
I like how survival wave 18 was intended for nobody to pass. However, in the event of somebody beating it, it would be nice if the level ended instead of just watching your party walk forever. (2 fairies, a knight and a cat; don't expect to kill much, but you'll be nearly invincible)
Am I the only one here concerned that pigs, purchased for a dime, are running at 3600 MPH? I'm personally shocked that those bears, wolves, and birds have time to react!
