Fuck it I'll do this as a separate comment.
Contrary to what some people might have thought, no, I didn't abandon development.
If and when I eventually decide to stop updating (with UE 6 or whenever Tim decides to turn everything into the Metaverse Circus of Only Fortnite Game Modes), I will explicitly say so and remove the ability to buy the plugin.
The last two years haven't been fun for me. I have multiple chronic medical conditions that have landed me in the hospital,
or serious rehabilitation for long stretches.
At the end of the day, I'm usually too exhausted or even physically unable to do... anything, even if I want to,
so I need to take it one day at a time.
That's my new reality.
tl;dr: Everything takes a lot more time than it used to.
So, I'm sorry it took this long for me to post the 5.5 update, and that I skipped the 5.4.1+ ones (which I thought I tested with the live 5.4.1 binaries which seemed to work fine at the time and didn't require anything from me, like back with the 5.3.1 on 5.3.2 version, but perhaps I only tested rebuilds. Things got... hazy for a while), but I couldn't give you a timeline for fixes, or promise anything until it was actually done, so... yeah.
Anyway, the new Not Fucking Dead update should fix all the listed problems from the last... 6 months.
Here's to not being dead.
Merry Christmas
