• Major performance optimization. Now mod pack requires significantly less RAM and will give significantly better performance with the same PC characteristics.
• Major bugfix. A lot of bugs fixed.
• Many features added.
• Replaced FTB chunks with Xaero's mods with Open Parties and Claims system. Because FTB chunks had a lot of bugs/performance problems/ and now Xaero's mods are better solution for map system.
