Thanks!
I just tried it on my game here and everything works. I can buy whatever I want from Aimee's Goods. Are you referring to a particular item?
Durasteel and ammor are limited to once every week. Maybe that's why you think it's glitching?
nope, it was fasteners actually. I buy it once and it stays this way after that. Also, after this, if I bring the cursor to any button, even "back" button, they start blinking as if they got highlighted on and off. Everything was ok for me as well, I noticed this glitch yesterday with a previous version of the game. Maybe not a common bug, still, it happened to me.
UPD: I found a way to ease this glitch. I switch to durasteel with a double click, and in a while the screen shows it's proce instead of informing it is added to inventory (doesn't work with other types of goods). Then I can switch back to fasteners and buy it one more time. I must repeat this procedure before every bunch of fasteners I wanna buy. Still not very convenient, but well...
