unfortunately nothing much can be done about it until the next updateKeep getting black screen/stuck on step 482 for some reason or another, happened at step 479 once as well.
best advice would be to download 0.37Final from the OP, use that to play pass that section and then carry on from there on 0.38.
or if you're ok to bypass 0.28 completely, you can download the "complete 0.28" save from the link in my signature.
