Dont have a go at EB and the designers mate, the problem will likely be that there is a compatibility issue somewhere. Its basically impossible to make a game thats crash or mistake free; the reason EB is slow and is prone to a few CTD's is because its one of the biggest and most detailed mods out there, and they fit it all around a basic and pretty unnegotiatable skeleton; R:TW. The most common reason for CTD's in EB is something to do with rebellions in a settlement, and is explained many a time on this forum. Try searching for threads of similar problems, and their will likely be a sollution somewhere. Dont blame it on the EB team though, they do their utmost best, but some problems are just out of their hands. They will likely not respond if you post an unhelpful or attacking thread.
