Ahh i saw the problem, thank you so much, it is because of the changes I made to the dropdowns, I had updated code for the sell dropdowns but not create ones. It is fixed now so next time I update, it will work. At the moment no one will be able to create any compounds properly except the max possible.

By the way if you want to test anything or 'cheat' you can press numpad '-' to see a cheat menu to allow you to get to any place in the game, but id advise you start a new save before doing this.
I have fixed the dropdown for selling.
Unfortunately the other issue is 99% save migration related. If you could tell me your pioneer name at cosmicforge999@gmail.com i would open the save and use it to test code changes to save migration, until it works again, nothing will be changed or lost for you but i have seen this issue already and its hard to reproduce it, so would be useful! Incidentally it is not happening on new saves, well I dont know the exact steps, but I can have a battery and use that to run the space telescope. Ill take a look.
I have reproduced it on an existing save. It happens anytime you start the space telescope searches, any of them when the power is on, it breaks. Its 100% related to a variable i havent included in the save migration code. Ill investigate, but it works on a new save, as it should. Thanks for bringing this one to my attention.
