Champions bundle made me go negative on owl tokens

I bought the champions bundle in overwatch two and leading up to this i watch a lot of matchs in the owl grand finals i did not get my tokes so i was only barely able to get the bundle but when i did btw i had 575 tokens before hand i went all the way down to -175 despite the bundle only costing 500 i dont know if you guys are aware of this or not but i advise you not to buy the bundle unless you expect to be negative on tokens afterward
