Bug Report

Placing down map frames on the floor in grids may, after some time, cause them to flip vertically, no longer displaying their map contents. Breaking one of the affected map squares will cause the others nearby to revert temporarily. But they will inevitably pop back up again.

I have now moved the map twice, after noticing the map was only doing this in a certain chunk. So I moved to another collection of chunks. But now TWO have been affected by this unusual behaviour.

Expected Behaviour

I mean, the map frames shouldn't really do this.

Possible Solution

I have checked Bibliocraft to see if this is an issue they've ever reported, but I am seeing nothing, no mention of any issues to their map frames regarding this specific issue.

Steps to Reproduce (for bugs)

1.Place map frames down on the floor in large grids (Anything larger than 3x3 or so)
2. After a while (I cannot easily estimate an amount of time required), they will adjust to this broken state. Frustratingly, this also makes providing logs very difficult as the distance between incidents is so rare.
