Anybody else having problems with the 11 gold keys thing?

[Edgecrusher43]

I have 11 gold keys, tried to open them at one time to get the SR Unit, and it tries to make me buy more gold to get them and won't let me use the keys. Anybody else experiencing this?

you can only open 10 at once if they are in your inventory. to open 11 you need to use 600 gold.

It makes you buy the keys for some reason rather than let you use the keys you have.
