Error; cannot run a push matrix more than 32 times, then "target VM failed to initialize" - processing

Question

I keep getting a "cannot run pushMatrix more than 32 times" in the middle of running this sketch. I'm aware that this can be an issue of having pushMatrix(); calls without a matching popMatrix(); but I don't see it in my code. Any help appreciated.
For the record; I'm aware this code is not very pretty and could be refactored extensively. I'm still new to programming and this is just an ongoing project I've been working on since the day I started coding.
Thanks again for any help.

Answer 1

Getting rid of the two calls (push and pop) inside the function drawCounterspin() seams to solve the problem without side effects. But I don't really know why... I have sen this behaviour before using push/popMatrix inside functions. If needed, isolate the call in draw, and not in the function, like:
pushMatrix();
drawCounterspin();
popMatrix();
Worked for me before.
