When I build a trade depot it automatically shows as two of the storage lots are used. As soon as I plop a second storage lot it shows that 4 of 4 lots are used and I cannot add any more, even though I only have the freight lot it comes with plus a coal lot. I've added a few of the mods from this site but I thought I'd ask all of you this question before I invest a huge amount of time removing one mod, starting a new game, and advancing to the point I could build a trade depot to see if its fixed or not. I'm only playing this way offline. Thanks for any help!
