So, I decided to try to go back and continue coloring my future pages of my comic, there's a ton of unreleased pages I got to cover and slowly getting it done.
I replaced the files, and coming back to check where I left off I didn't realized the thing reset from 2030 to this year and caused some issues that I had to quickly fix.
It is extremely frustrating doing these fixes, double checking the dates I set up and have a way to keep track of things (I put it into a text file and check off the dates I used).

Basically it drives me insane and trying to fight off the urge to put upload everything in large bursts but I am trying to build up an audience through keeping said schedule.

So, how else does everyone else had to deal with fixing their comic schedule release dates?

I update so infrequently that's not an issue XD

When I do the schedule I either use the computer's calendar or have one of those old style paper calendars at my elbow to keep it all straight.
My comic is supposed to update on Friday amd when double checking to put in reedited pages wouldn't you know I had put a month's worth on Thursday and had skipped a Tuesday update.
Constant vigilance. Since I am always editing pages in the buffer I do it more frequently than I'd like. Also double check everything when I add pages to the buffer.
Being so thorough cuts down on my anxiety. Once upon a time having this kind of attention to detail was a matter of life and death.
