[b43] Arena error message

[Robsoie]

During a victorious 60 waves Arena, using a Skeleton Necromancer (that had several minions onscreen) i ran 3 times during the whole game into this error message :

Code: Select all

error = "Lua Error: /engine/utils.lua:1452: attempt to perform arithmetic on local 'x' (a nil value)\

seen = true
reported = true

As i doubt it effectively reported the error as it is saying it did (as i was playing with profile offline), i post it here just in case.

Seemed to be harmless as it didn't prevent the game to continue and the next waves to come for the 3 times it happened, and it didn't prevented the character to win that specific Arena game.
