Many long-standing bugs in the previous release have been fixed. Some are still pending a fix or need further confirmation, which will be listed further down. Please use the latest BKCommonLib (1.11.2-v2), which includes some of the below bugfixes and more. This build supports Spigot 1.11.2 and 1.12-pre5, 1.12-pre6 (tested)

Bugfixes:

• Fixes a bug where you could not interact with minecarts
  
• Fix minecart displayed block data wrongly applied
  
• Fix errors when loading collision modes
• Fix teleport sign not always teleporting
• Fix vertical rails not triggering signs
• Fix spawn signs not working on vertical rails
• Fix minecarts not playing any sound when on vertical rails
• Fix collect/deposit signs always dropping items on the ground
• Fix furnace minecart sound loop not playing
  
• Catch errors in third-party rail plugins (such as TCHangRail) and disable such rails when they occur to prevent hard-to-track-down errors that render TrainCarts unusable

Changes in minecart rail physics:

• Minecarts now collide with low-hanging ceiling blocks to allow vanilla-style minecart piston stations to function. This can be turned off in the configuration
• Minecarts no longer go through blocks perpendicular to a curved rail when derailing, causing them to be stuck there
• Minecarts no longer go through blocks above a slope
  
• Vertical rails have altered physics when going from slope to vertical, which may have very slightly impacted their height reach. Check your attractions!

General bug reports that have been verified and fixed:

• "If you place property speedlimit signs on a ladder rail (looping or dive drop) the cart won't listen to the sign."
• "Minecart goes through the wall when encountering a derailed curve"
• "Furnace in not working"
• "train spawning on ladder goes either up or down, no consistency"

Some things that may have been fixed:

• "Detector sign not working - stays active" (failed to reproduce)
• "Cross world teleport not working" (failed to reproduce locally)
• "Trap Doors show off at an offset" (they dont appear to)
• "Cant put multiple signs underneath each other" (appears to work)
• Fireworks causing strange issues with minecarts. Changes have been made to prevent it, but it is not verified as fixed.
  
• Several odd station sign related physics bugs, which are hard to reproduce because of how large the track has to be. If you encounter these, for now try changing the station sign 'length' so it does not launch too large distances.
