Mausoleum is useless

The thing is $200 every 8 hours is really close to nothing. I find cash extremely easy to make. Whereas the building I bought for 90 donuts just to spawn me zombies dousn't do that anymore. $200 every 8 hours VS being able to squish zombies and having my town swarming with zombies turning my residents into zombie counterparts (even when they are doing jobs) seems much more enjoyable to me even if I get nothing for making the zombies go splat. It just would make the game have more variety. If I could get my 90 donuts back, I would, and spend it towards buying more characters that actually interact with the town.
