Ok, for starters i dont know if this has been posted before, but if not i hope this helps this seems to be a major issue
Step 1: Download the K5 patch
Step 2: Replace your Script_bin, collision.dll, Arcemu-world.exe and Arcemu-logonserver.exe in your server folder with the ones from the K5 patch
Step 3: Download the K5 dbc files (tested and working)
Step 4: replace your DBC folder with the new DBC folder from the link i gave you
Step 5: Start your arcemu-world.exe and Arcemu-logonserver.exe files and it should run through with no errors
Note: The talent bug is usually a rev2496 problem. idk if the fix works on anything other than rev 2496. but feel free to try it
