Therka, the whole market city and my base (I think every old buying plinth).
There were stones or wood and bones and coal in them. Now they are empty with this glitchy square. I just tried to place a fibre leave in it. It's in them but there's nothing shown on the plinth (not even the glitchy thing).
Oh and my old ink extract has the same green like fibre, but the new leaves are red (looks good by the way).
