Consultants not unlocking
I've played up to Level 5 and only 1 consultant is consistantly unlocking - the Tenki guy.
Twiggy pop isn't unlocking and is not available to bring into the game in later levels despite her planet being at 5 stars and the story complete. Same with the Vizyr(?) one in the big vegetable level. The galaxy was also not carrying over the loamite unlocked objects from level to level, and until I turned off steam cloud saves, wasn't actually saving my prior game progress.
I have the latest DLC, but only just got the game.
Sorry to hear you're still having this issue. While fixes have been deployed for potential causes of the issue and other protections put in place there's no way to confirm whether the exact cause has been identified in your case.
I understand this is frustrating and can only apologise for that.
Can I confirm the following:
If you can confirm the above and the problem is still presented then I'd like to check a few more things.
If you've verified your files and confirmed 2 and 3 are not the case then all we can do is go ahead and try and get a more comprehensive demonstration of the problem.
Please submit all these saves to us. Hopefully at some point in all of those saves we can spot something which would indicate what might have gone wrong.
If you can do all of this in one session that'd be the best. I apologise as I know that's a lot of groundwork but we genuinely cannot replicate your issue, which means at this time we have no idea what the cause could be.
