Make a stone tile without any stone...

[Amigopen]

I tried to place stone on the floor, and I forgot that I didn't have any stone. When this happened, it said "You need a Gold Nugget" or something appeared. It isn't that major, but I just wanted to point it out, since you use stone to make stone tiles, not gold nuggets.

Maybe you clicked 'lay gold' instead?

No, this is a known bug.

I don't have that feature enabled for me to use.

If you click 'lay stone' on grass or dirt, it'll lay a stone. If you click it on an already paved tile, it does 'lay gold'.

This is a feature, not a bug. No?
