fix to corporationDevelopments
There's an extra <<set $drugAssets -= 500>> under the sale link outside of the $drugAssets>1000 conditional. This can cause several issues, such as reducing the assets even when there are none to sell (potentially sending them into the negative), and doubling the cost of drug sales. Both occur without compensation to $corpCash.
I've made the appropriate change in the last merge under my personal tweaks (the other tweak in the previous merge may not be to your liking), but all that really needs to be done is to delete the extra code.
