Alright, thank you - found the issue. Technically it isn't a softlock - you should be able to manually type 'End Conversation' and be able to continue. I have a fix up on subscribestar, in a public post, same as I did with the guide - I'll wait to see if there are more bugs to fix first before constantly asking the mods to amend the thread with new links.going to the representative and choosing the finish option puts you in a blank screen
Funny, it seems to be specifically level 4 upgrade (the 800 one), that goes to a blank screen if there's no money. Maybe later ones too but can't check right now.
