Affects every 1.8.1+ version (shortened instead to post many comments saying "Can confirm in version")
I didn't had any minecarts with commandblocks. I had a impulse command block activated by a observer redstone clock which after places the train but when a normal minecart existed, it just placed the train on the command block's position rathern than the minecart's position.
Actually the minecart is a regular minecart not a command block minecart. Oh, wait i can use it to do that.
Well i do not understand why this happens and only solution to do when it stuck on saving world screen is to shut down your computer/laptop.
This happens with any version and due programming of minecart, minecarts will always face one direction independent of where it was placed, i would like if minecarts will face direction in where player placed them it would be better like the furnace cart hole always face the front and same for chest cart, the iron thing on front will always be as front of chest cart
Do this as fast as possible because of this i cant play minecraft and i am bored without MC
It is not required to spam "Can confirm in [version]". This issue is the oldest issue that is still not resolved on Mojira, and because of that, this bug haven't been yet fixed and will be in all versions until Mojang will fix it.
