"autobuy" inventory slots for sentinels only worked once in foundry

[sulusdacor]

i rebuild the 3 normal sentinel wyrm,shade,carrier. i sold them before and filed my slots with others. so i had zero slots left. when i took the first out of the foundry the game offered me the normal message "insufficient slots, do you wanne buy new slots ...". bought two could get my 1st out of the foundry normaly. wanted to take the 2nd one out and i just got "insufficient slots" no offer to buy more slots. manually going into my inventory and buying them worked.

i did try to exit the foundry and enter it again, but got same error. i did this in the same "session",meaning it did not leave my orbit in between this.

in the past i build more then a few weapons i sold previously and had no inventory space left. when taking all of them out of the foundry i got the corret offer to buy more slots in the same session if my slots were full, so i assume the above is a bug.
