In Canister.cpp, a comment says "no doozies in the 50 buckazoid category", which contains Rad-Away, regeneration and healing. However, plasma and poison are after the 100 cost group, but have a price of 50 specified. Either poison or plasma should cost 100, or the "no doozies" comment is wrong and they should be moved to the 50 zoid group.

Not sure whether I intended my comment or my code! Let this be a lesson to you young programmers: never comment your code to avoid the possibility of self contradiction! :-P
