Bug minimap button in ver 1.8.7a

[turnover2]

With the version 1.8.7 the button is at the minimap. With the version 1.8.7a the button is gone. I have classic ui enabled on my interface, perhaps this is a problem?

With ver. 1.8.7b all is fine again

Hi! I hope it's still fine after updating to 1.8.7c?
