Running the UC mod on a private PVE server on SurvialServers.com. For some reason I can place one or two UC stone foundations, then I cant stack any more. I have tried rebooting server, restarting Ark, replacing the first foundation and so on. Also, this only seems to be a problem in certain spots on the map (no where near a cave or respawn point). Is this a mod issues, Ark issue or server issue? Thanks for any input or suggestions.
