Thanks for all the suggestions and assistance, i think ill try this, from what i can see its Xie's mod that is using this ID for modified crops, one other question though, if there are further conflicts would this be in the error report? or when i change this and there is another conflict will that only show then ? and i would need to knock this off the list one by one ? sry for these questions which probably seem fairly noobish but this is the first time Ive had to do this .
It crashes at the first block ID conflict it runs into.
So, one at a time. I don't know of a way to see all block ID conflicts without manually checking them all.
