I read through the entire thread, but don't think I found anyone with a similar problem.
I downloaded ViolentSpatula's version on page 2 (post #20) and proceeded to set it up with THIS Reddit guide.
I believe I followed the instructions fully, but it seems that when I open a battle video to view the details of my hatched eggs (or anything, really), it will show me ALL information EXCEPT the ESV. I tried pretty much everything I can think of. I toggled and played around with the settings; I re-set up the tool and re-broke my BV Keystream; and I downloaded every available version in this thread. Nothing I do will show me the ESV.
I guess I did something wrong, somewhere... I just don't know what. Obviously, I didn't screw up too bad, because I can view all the export strings except for ESV (and box, but that is obvious) when using a custom export style. It seems that everything works as intended... except the ESV portion.
This is the default export style:
If there is anything I should do for others in order to solve this problem, please let me know. A recommended upload site is also appreciated in that case.
Additionally, I am mostly around Smogon in case you wish to contact me more... often. My username is also Sakuretsu over at Smogon.
