Miscellaneous Fixes

I originally had planned for this branch to be a group of miscellaneous fixes, but I proceeded to forget about it for like 2 weeks, so might as well get it in now since I'm cleaning up my local repository to prepare for the OBT.

EDIT: I just found another issue I can fix, so I'm reverting the title of the MR to its original intention

Current Fixes: Fix typo in COND_DESPAIR status message Verify amount variable is not nil before checking its value in BTL_getMacca
