I went from smaugfuss 1.9 to afkmud 2.1.5. I enjoy this codebase but I seem to have a problem. I use cygwin. I could do a hotboot on smuag with no problem however I get booted and this error pops up

could not decompress text from mud: invalid code lengths set.

Did not see anything on the forums so any help would be great. Point me in the right direction with a hint and I can try to figure it out.
