Hello again everyone.
Today I've released the second hotfix for Testing Build. This hotfix addresses some issues with the marketing system in the Mega Menu. I've fixed the ever increasing costs and the inability to zero out costs. You may have to start a new game for this hotfix to work.
There is still some issues with the Marketing system, but since I'll be changing some stuff in 1.19.2 I probably won't put anymore effort into hotfixing the old system.
Thanks! And enjoy!
