I'm at around the Year 4 mark of my career. I need to develop specifically the ICU, Reshaped Combustion Chamber and Fuel Injection System (Efficiency). However, when I try to develop the upgrade it selects the option, but stays on that menu and won't proceed with the development. I'm able to move the cursor around again after but no matter which option I select it won't move forward and develop the part.
Additionally, when I check the Assign Upgrades tab, whenever I press B to back out of the menu the game apparently soft locks and won't let me do anything after. Unable to move the cursor or back out of the menu. I'm forced to hard reset the game after.
Has anyone else encountered this issue? If so is there any fix or something I'm doing wrong? Help would be greatly appreciated. Thanks in advance!
