Hey there Grimzzy,
Can you tell me which menus do you have this problem with? Only in Rumia’s shop?
Its most of the menus but to name the ones I have found so far, Rumia for one not letting you sell, back out or buy items, inventory buttons don't work as well not being able to back out the menu or select Items, gallery buttons don't work at all you can't select any creatures or back out the menu and equipment menu doesn't let you back out to previous menus or select your items.
So far these are what I have found so far on the Android version, I hope this helps.
Thank you for the feedback, I was able to replicate this. This is an issue in the game engine with scroll windows. There are good news however, there is a way to mitigate it. I’ll test it out and implement it on the next version :).
Meanwhile, there is a sort of workaround on the current version, which is if you spam the button, eventually it will press, sorry for the boring quick solution :(. This is like a race condition between the scroll bar and the buttons. It seems to only happen on the menus you mentioned, other menus work fine because they have no hidden scroll bars.
