Wow, that was a fast fix, i´m impressed on how quick u addressed that issue. I tested it on my machine after the update and now the transfer between the hauler and all tiers of miners works.
Also i noticed the Miners always have exhaust fumes active, even if they do nothing(might be intended). The Hauler seems to have high end exhaust fume cleaning mechanism working (no smoke at all:) ).
Another strange behavior is that the miners seem to have flickering track and front tool animation which occur in pulses of one second. This can be seen on all tiers of miners and might be necessary for reasons i dont understand cause im no modder. Also the animation of the front tools of all miners is bound to the movement of the miner but stops when the miner is actually working which is confusing me a bit :).
However, pls dont be offended by my mentionings, i know modding is hard work and some things may not be possible. This mod and the whole AAI-Mod-Series is awesome and u did a realy nice job here, so thank you for your work.
