There's a bug that occurs whenever someone instnatly changes pet, or when pet classes exit veichles. This is because of an assertion in GridRoster that assumes that if a unit pet event occurs the pet should either be the same as the previous pet or nil.

The easiest way to test this is to party with a Warlock and have him cast eye of killrog.

Here's the error:

Message: Interface\AddOns\Grid2\GridRoster.lua:173: assertion failed!

To fix this, remove line 173 of GridRoster.lua, seems to work fine regardless.

Fixed in rev305.
