In Munchkin Cthulhu rulebook (
http://www.worldofmunchkin.com/rules/cthulhu_rules.pdf) there is an example of combat at page 5.
A cultist is in combat with a monster, and plays a Canned Meat card that gives a +3 bonus. Another player plays a Curse, that cause the cultist to lose its class and all associated bonus.
In this example the cultist loses the bonus from Canned Meat too, and it seems wrong to me.
Am I missing something?
