EnderIO: Found the following problem(s) with your installation: * An unknown AE2 API is installed (rv3 from appliedenergistics2-rv3-beta-6.jar). Ender IO was build against API version rv2 and may or may not work with a newer version. This may have caused the error. Try reproducing the crash WITHOUT this/these mod(s) before reporting. it This may be the cause. Or chisel blocks. At least thats what I found however this may not be the case. Usually when I crash a hard force update works alot of the time. You could also try to add more ram unless your over 4gb dedicated.
ok force update and run without fastcraft no crash. anyway i have removed the area with barrels as well. thanks for the help.
