[1.5.10] Whitehoof Charges Graphics Bug?

[Relic]

Running orcs, fighting aeryn when this came up and blanked the screen. Had to 'kill' the game. Thinking charges is whitehoof charges, though could be brawler power up.

Lua Error: /mod/class/uiset/Minimalist.lua bad argument #1 to 'charges' (number expected, got nil)

Not sure if it was a one shot lock since the error kept coming (in terminal) up the same and the screen went blank. Wasn't able to reproduce it one the next battle attempt.

That is what happens when there is an error in the display of a timed effect.
