LikeFireflye had said FP is way known for it's crashing. It's a pretty big map with lots of fluffies in it plus this game is starting to get a tad old now so there might be a good amount of crashing once in a while. Trust me I crash a lot, but there is nothing we can really do about it. ^^
Thats alot of re-downloads floof, lets see if we can ease some of this stress c: FP is known for crashing, yes, but not for everyone, it depends on your computers CPU and RAM. The faster the PC, the better it can handle high demands of graphics. It might just be your PC or the map might actually be full, disconnected for some reason, or just being buggy. It's always best to remain paitent. You could try changing you rendering system as suggested above, or closing other applications that might be taking CPU from your games demand.
