Thanks for that the zombies getting stuck at holes I noticed last night. I think it had to do with me skipping coinc checks during a player jump/fall. Still have to confirm. I also have disappearing zombies on the known issues list.
V0.51 reduces the performance drop with more zombies but I'm currently working on that at this time.
And I'm using a very primitive loot balance system with RANDOMIZE. That's going to be a challenge since I don't really understand the other "random number methods" other folks use to get better results.
I think I'll have to scrap the random number thing and use a more mathematically precise method to balance loot spawn. I treat zombie spawn as loot when creating levels (see _LDS in the source code)
It's great that you are play testing and posting your results. I really appreciate it. So thank you.
My goal now is to finish up these things ( and then get the new zombie in. Once I'm there, I'll go beta and focus strictly on optimizing everything. Then the final touches.
EDIT: Updated OP with new Known Issues and To do next steps.
