When you turn on the mod, after a minute of playing, a message starts popping up:
-----------------------------------------------------------------------
Field '.TransportLine.m_vehicleInfoUniqueString' not found. [System.MissingFieldException]
-------------------------------------------------- ---------------------
If I press OK, the game goes on, but after 5-10 seconds the message pops up again. In this case, the mod works.
Harmony 2.2-0 (Mod Dependency)
TM:PE 11.6.5.3 STABLE
There are no mods from the incompatible list.
Tell me, in which direction to dig?

The only thing I need from the mod is the ability to change the number of passengers in the transport, maybe there is another mod that can do this?
