Hello, 1st post, but found out that the game crashes while loading the newest version (1.5.3)
Mentions pyHightech to be the culprit (odd, since I updated this one ) - and complains about missing item Duralumin.

I simply downgraded to the 1.5.2 and able to play again.

Same problem here.

I checked the Factorio logs, and it seems that version 1.5.3 is a "bad zip file". And indeed, if I try to manually extract the zip file, it fails.

ive uploaded 1.5.4 that should fix the crash issue that 1.5.3 was attempting to fix and whatever the hell went wrong with 1.5.3

Works like a charm. Thanks!
1.5.4 is not causing this.

Great suggestion there drschwamy, did not try to unzip and figure out that was the cause...

Fixed with 1.5.4
