This is probably a client-side issue, from the information you've given me. In order to fully gauge the problem, could you ask someone else to try on your server? If that is the case, it would be a minehut-side problem. If not, like I said before, it would probably be due to your account.
I'm not really sure what the problem could be, seeing as this is definitely isn't a common occurrence. It could be due to lag causing crafting not to work, but I'd need more information to help. Maybe try using a ethernet cable or moving closer to the router you're using.
I'm sorry I couldn't help as much as I'd liked to, but I've never seen this as an issue before. Try what I suggested for both troubleshooting and suggested solutions. if anything happens, come back and I'd be glad to help some more. I'm sorry there was nothing else I could do!
