I have the exact same problem on my MacBook 2019. Only started last week. Legion TD was affected moderately, units could be build but some would remain invisible and not selectable. Footmen was completely unplayable. That is because footmen units are invisible and unelectable entirely. This is true for the normal (non-custom) maps as well. Just generally no fun at the moment. Either:
- Some units are invisible but I can still select them
- Some units are invisible and I cannot select them
- Some units are colored very strangely (completely pink, red, yellow, etc.)
Do you have similar problems? If you find a fix, would be awesome if you can share the solution.
