I crash when I try to log in to my FTB Unleashed SMP server. This started recently after defeating the wither, but I suspect it had nothing to do with the wither. I have had fully constructed iron tanks (1 with lava, 1 with oil, 2 empty) for 2 days and have had no problems, however I have done extensive testing over the past 4 hours and I think I've narrowed my crashing down to the tanks. When I disable railcraft I can log on fine, when I destroy every single railcraft wall/gauge in my chunk I can log in fine as well. I tried replacing the iron tanks with steel tanks to see if it was an ID issue and even they crash me. The way I can temporarily log in successfully is to first log in to my single player world, which makes no sense to me.
tl;dr I'm crashing when I try to log into my previously working server. I think it's caused by Railcraft tanks, maybe. How can I fix this?
