(please include information of what you did, that lead up to the bug, what you expected to happen there, and what actually happened, then move on to describe below:)
Whenever I use the Blackguard Bull's Strength on myself, any prior castings from wands/potions/other characters is wiped and I'm left with the +4 from Blackguard Bull's Strength. If I use a potion after, it wipes the +4 from Blackguard.
Steps to reproduce the Bug:
* Be a Blackguard, minimum level 2
* Use a potion of Bull's Strength
* Use Blackguard Bull's Strength
Expected Result:
1d4+1 STR from potion stacks with +4 for 1d4+5 worth of STR.
Actual Result:
+4 STR
