Either I'm missing something or it is impossible to progress with angel/py/bob since I need to make the red science but to make it I need incubated petri dish and to make that I need petri dish which can only be made after alien bio processing has been researched for which I need red science.

that shouldnt be locked. can you provide a save file so that i can sync up mods/ mod settings and see what needs modified to fix that

Sure I put it on google drive, I am using a lot of mods though.

Same sort of issue here too....with Angels/Bob ...can't craft red science because I need glass for which I need electronic circuit boards for which I need science 1.... from what I can read down in this forums a LOT of people are coming across this....

Hi in response to the petridish problem i found if you go in this folder Application Support/factorio/mods/PyCoalTBaA/prototypes/angels-mods/prototypes/overrides (then open overrides-updates with text editor) and you go to the bottom of the file then you change follow line:
-- fun.global_item_replacer('petri-dish', 'empty-petri-dish') to fun.global_item_replacer('petri-dish', 'empty-petri-dish')
this reenables the progress and avoids the deadlock at least for me
@kingarthur is there a reason this line is disabled? i understand i have an obsolete recipe now in angel bio (from glass to 'petri-dish') but for the rest this shouldn't give any problems right?

You'll eventually run into another issue with them later not being able to make a dish you need to make. Might be ok for a while. I dont remember exactly where the issue was.

I'm currently reworking a large chunk of pyal then I'm planning to lock in a specific setup of py+angels and fix all these little issues. Rough eta of sometime in April.

ok thx
