I've been waiting over a month. After releasing the new beta which doesn't repair the problem of 'Polish locos stutter' which I reported to you, you closed the Trainz doors for Polish users. The last version which works ok with Polish locos is 105100. You say this is the Polish not efficient script that should be blamed. But it's impossible to repair thousands of Polish locos!!
My statement is - DELETE all my assets from DLS, I don't want to participate in this unfriendly environment anymore, I quit.
