Unfortunately, there are some maps this will not work on, not due to your pack but due to map makers. So far, one I lose the channel for all the grass but I get the crops and the other is a 16x and it just won't take it. Too big of a map.

I don't know how Giants programmed thei Engine for FS25, but it should have been ready from the beginning for 64 fruits (they added this back in FS22 year 2), also support for 16x maps or bigger... But why I complain of that, when the AI can't handle 2 or 3 harvesters on the same field (like Courseplay)...
