brownie compile err’d out with this stack trace:

IndexError: pop from an empty deque

It doesn’t have to do only with the contract size being exceeded because I removed some small parts of the code and it worked, but the size was still exceeded. But it seems to happen when the size has been exceeded or is very large.

How can it be fixed?
