MTR 4 is still in active development, and there are some issues and features to be completed.

You can help the development of MTR 4 by contributing to such area.

• BVE Sound breaks if player is outside loaded chunk (In per-car basis), where only a short period of sound is heard.
  • Reinstating the train (Going out and back in the area) would fix the issue, but F3+T does not fix it.
• Action bar and destination shows the destination station's custom destination, instead of the next station's custom destination
• NTE Rail flipped to the other side after upgrading to MTR 4.

• Can't get BVE Sound working with the legacy resource format? (To be investigated)
• MTR 4 will peak the CPU to 100% with certain CPU Model
• Elevator position will be off with certain mod combination

• MTR System Map's Direction Pane is incomplete. (WIP in#6)
• Disable Next Station Announcement does not work
• Re-implement Manual driving
• Hide Route not working on System Map
• Missing Ding Sound in Elevator
• Single Arrival Vertical PIDS not implemented

Some custom door sound does not get played for whatever reason, to be investigated
