sometimes surf can be nil, i'm not sure what the correct behavior is in this circumstance so i can't adequately submit a PR for it

Patched in hotfix.
Surfaces are a bit buggy in many cases. Willox said that he couldn't locate the problems I gave him, after he added the function.

Sadly unsolvable for now, but added a safeguard against it causing errors.
