Three issues with Abandoned mines fungus/red & yellow
spores:

1) Deafen/Insanity/Forget lands 100% of time. No chance to
avoid/resist them.
2) They add up as extra affects (I got 2 insanity affects in
log below).
3) They can make the affect permanent (i.e. Physical effect:
'insanity' for -1 hours.)
