Handymen can get stuck when heading toward litter

[lot61]

Especially in queues because they are usually the only winding paths, handymen can turn back and forth when litter pops up nearby. Eventually they seem to snap out of it, but it often goes on long enough that the paths become absolutely disgusting. In a test that I did, the handyman heads back and forth along the marked path. This happens in vanilla, too.

Known issue, you can find it on github. For now, you can work around it by using patrol areas or waiting for another handyman to clean the puke.
