Issue in Bloons Super Monkey 2 - Bloon Dunes Stage 5

[Luna]

I recently uninstalled and reinstalled my game in attempt to see if I could reset my game data, it didn't work but that's not the issue. I just tried to replay stage 5 of bloon dunes and the phasing bloons in the first and last parts of the level don't show up, only their force fields do. When this happens, my game lags out pretty bad too. I have tried enabling and disabling hardware acceleration, and both software and hardware modes.
