*Regen Effects*
This week we corrected a bug that caused regen-type spells (e.g.
Regeneration, Chloroplast, Regrowth, etc.) to overwrite DOT spells. As
a result of this fix, players can no longer accept a regeneration spell
while under the effect of a DOT. However, if the regen spell is already
in place, the DOT will stack, but not replace the regen spell. This
will allow users of beneficial DOTs, such as Call of Bones, to continue
using their DOT while under the affect of regen.
