Do this need to be reported to Eovia for a new patch. Hopefully they can provide a patch that would let other PCs work on new tiles while one or more PCs still working on existing tiles? My concern is that if the PCs finished with all tiles in a frame and one or more PCs are still working on existing tile(s). As a engineer programmer, I would want unfinished tile(s) to split workload with PCs to finish it.
