Need more Info which version ?? SSP or SMP or Bukkit ?? which forge Version ??
So I'm testing a new version before I published.... Major Bug of the size would be noticed immediately
I'm having this issue as well, with SMP. Both server and client are running Forge 3.3.8.152, and MFFSV2_beta2. I am able to open the GUI and activate the MFFS machines normally in SSP, but not in SMP.
