Having problems is an understatement.

Now I can't send tokens because intrinsic gas is too low, even though I set it at 44 gwei - WAY above what the
https://ethgasstation.info/ is telling me. I wish my token would come up with a decent wallet already cos even holding it on my Nano, I still have to use MEW to send it anywhere

Try again later, maybe the network is congested again, ( though I'm not using it now ).
I don't know, but personally even before I haven't encounter this, I'm using the default gwei and if course the gas limit is automatically adjusted depend on the amount you'll send.
Just store the coins that you're planning to hold for longterm in your nano and use mew for storing the coins you often trade and with that, you wouldn't have a hard time. Just a tip.
Shall we be worry about it? are the dev team leave the project?
Don't be ridiculous.
