[Bug] Can't sell spaceweed (Solved)

[NukeACitrus]

I seem to have some problems selling spaceweed. I have 1k in my hold, and there's a buy offer of 200 on the station I'm parked at. On the selection-screen that pops up after docking, I select "trade", then pick amount to sell and click "sell", but nothing happens. The buy offer number is the same yellow as the item name, that just indicates it's illegal, right?

I also tried talking directly to the black market trader and sell it that way, no luck.

I've tried selling on multiple stations, no one seems to want to buy my stock. Any ideas on what might cause this? Is this a bug?

[UPDATE]

I tried lowering sell amount to 1 less than buy offer, selling 229 when there was a 230 buy offer. This allowed me to sell the spaceweed, and the price offered for selling space weed updated accordingly.

It seems that trying to sell the maximum amount prevents you from selling, but if you lower it everything works fine. Odd
