This has happened to me twice now. I keep an exact amount of the spawn speed buffs around incase i need them for something, Those numbers are 96-48-32-16 from common to epic.

If i end up with more from opening chests i spend them down to that level again.

The bug seems to happen after i spend some to go back down to my default level then the next day, after both a reset and a browser close and re-open i notice my count is down to 79 on commons rather than 96.

It also happened to my uncommon and rares ones a previous time, spend them down to the right level and then the next day they are 5-15 lower than they should be.

Am i losing more buffs than just those i keep at a certain level? Could this have anything to do with linking my account to steam a week or so ago?

yep, that sounds about right, does it say i used something like 10 or 15 or something like 30? because by memory i went from around 112 to 96, then it later showed up at 79 without me using any more.

yeah, thats the problem, i used less than half that. im not looking for compensation. Just keep in mind that there is a problem. I will document whenever i use speed buffs and how many i use and let you know if i have the problem again ok?
