Hi.
Game halts, when I click on a big blue belt on a main bus, but sometimes works i think because of small branch of belts (? idk). Pipes works well.
Windows gaves me Factorio is not responding message.
I've Pipe vizualizer mod, but it's disabled.
Also I couldn't find error messages on *.log files. There is only startup messages.

Oh, this time game continued after a couple minutes. I was on a browser.

Looks like memory leak.
Sadly after 15-20 minutes idle game gave an error.
