Factorio version 0.17.4 but it was in 0.17.3 also (didn't checked in previous version).
Log attached.

There is a little problem with attack alarm message in polish language version. The message looks like below:

In polish language version the train circuit wait condition can't be removed, because there is no remove button. IMac 27 5K 2017 and MacBook Pro 13'' 2017
