Crude Oil Storage (Info for other modders: ID version 36)

Station upgrade - Crude Oil Storage Tank, increasing both storage capacity and loading speed. The bonuses are identical with Coal Hopper

Update August 13, 2023
IMPORTANT

Station upgrades are defined in the game files in very specific way and there could be only limited number of them. Also, unlike other buildings in the game, there is a chance of ID collision between different mods with Station upgrades and also with vanilla game itself.
To prevent a collision with Subway mod, which has to use specific ID version otherwise it won't work (the mod will be released in near future), and also to free up some version IDs for vanilla game which is expanding with new content, I had to change the version IDs of my 3 station upgrades mods (4 upgrades in total).
This resulted in disappearing of the built station upgrade in your saved game, although the upgrade itself is marked as "built" on the upgrades tab of the station. Please use bulldozer on the now empty square (invisible building) and build the upgrade a new.
I'm sorry, but I didn't find a different solution to this problem, and I hope that I won't have to do this ever again, although I can't be 100% sure about it.
My mods should be fully compatible with mods from Hracicka and Tegaf and with ever expanding vanilla game. Sorry, I can't fully exclude collision with other mods containing station upgrades though.
If you are trying to build any (not only mine) station upgrade and it doesn't work (such as from Bigger stations +++ mod), this ID version collision is the cause. Only the mod author can fix it or you'd have to download the mod locally and fix it for yourself.
