When placing the railroad crossing arms large,med and small on the railroad crossing stand the game crashes, when you log in the crossing arm is placed, if you put a redstone to it , it crashes again, when you log in the arm is in the down position and making the crossing sound. Im using LampsAndTrafficlights-1.2-Minecraft_1.7.10 along with direwolf20 1.9.0 FTB pack
Edit: Seems that if any block is placed next to the crossing stand it crashes but only if the crossing arm is attached to the stand (which also crashes)
I've never heard of this or seen this problem before, can you give me a crashlog?
