[1.18 HF1] Plot Gigurum doesn't trade

[desiriel]

The Bulk Gigurum I'm given in DeVries by the Republic of Cantera doesn't follow my trade orders.
I got it with roughly 2.800 meat and I ordered it to sell that at Gushing Springs. This trade order was effectively executed.
After this, I ordered the Gigurum to buy wheat at Fifteen Rays. The Gigurum arrives there but then it stops and doesn't absolutely nothing (no, there weren't any other orders in the trade queue and apparently the station docks weren't busy either). Loading the game, I noticed that sometimes the Gigurum didn't stop but simply kept burning in a straight line far from the stations and didn't answer my other commands.
Anyway the Gigurum is useless for trading for me as of now. I detached it from my squad and kept doing missions.

I have more or less the same issue here, and it still persists into 1.19. The Gigurum, when ordered to buy wheat in fifteen rays, will just fly about 30km out from the station and sit there. Haven't been able to test if it is just fifteen rays that it does it at, but when I cancel the trade it will respond to orders just fine.

Have you tried cancelling the trade queue and then remove the ship from group and re-add it.
Seems to have worked for me most times.

My gigurum has also completely stopped accepting trade orders. Have tried to reset, remove, re-add and issue new orders several times but the ship just sits there. Will follow me around though. Mind, this ship was given to me using 1.18 so I'm not sure if it's exactly the same issue.

Yeah, I've tried all sorts of various remove/add, re-add trade and such. I have a couple more I want to try with 1.19 to see if it works different there.

I guess my issue is a bit different as it does show the trade in the queue, but it just sits there. Either way, down with Gigurums!
