I was wondering when someone would point that out
This isn't the only case--there are a few other hypenated words that are not entirely consistent (or correct), because the first major batch of objects was all written during the 7DRL (under the serious time constraints), then I came back to it a year later and started working with it again, but didn't decide on a consistent way to deal with it...
The perfectionist in me has been trying to ignore it because I'll have to go through everything, collect the relevant info, decide on a system for optionally hyphenated words, and actually apply changes to numerous areas... SO, now that you've brought it up I guess I have to finally do that xD
Fine then!
