I'm having issues with AdvancementPlaques and WAILA aka HWYLA.
The current version of WAILA for 1.16.5 as of it's full release is 8.0.1 while it's beta version is 8.0.6 and neither one of them is working with the latest version of AdvancementPlaques and now requires 2.7.1 or
higher when 8.0.1 is higher than 2.7.1

Look at what's highlighted in the second screenshot which is it's beta version btw.

Here's the crash log: https://pastebin.com/L05nJTBR

For the time being I'm going to revert back to the last version of this mod that was working with WAILA (HWYLA) while I wait for this to get resolved.

One last thing, I've tried to dig deeper into WAILA to find it's true version and idk where it may be within it's files without messing up WAILA itself since I don't know if 8.0.1 or 8.0.6 are it's true versioning numbers and why I say this is cause as you can see in the first screenshot that MC is telling me that WAILA's 1.16.5 version is 1.10.11-B79_1.16.2.
Also WAILA hasn't been updated in months as of a full release version (Feb 1st)...

WAIT A SEC!
Does WAILA (HWYLA) use the same versioning as Bookshelf???
If so then why is MC telling me that I need the latest version of WAILA instead of Bookshelf for the latest version of AdvancementPlaques?!?
Let me see if updating bookshelf fixes this mess and if it does then I'll close this as soon as I'm passed mod loading....

Ah, interesting, I think I know what is happening here. This is an unfortunate case of multiple mods using the same mod ID but having different versioning. Waila, Hwyla, and Jade all use the mod ID "waila", but the version requirement in the latest Advancement Plaques update is based on the versioning of Jade (it is the most recently-updated fork of Waila).
In order to fix this, I will remove the version requirements altogether.

This has been fixed in fa2b8b2. Look for Advancement Plaques 1.2.4 on CurseForge once it's available. Enjoy!

Thanks for fixing the issue, But I'd thought that the versioning thing as of Waila was based off from Bookshelf library mod which is owned by the same owner of Waila (Hwyla, Jade) i think cause in the screenshot above looks like bookshelf's versioning.
Also I don't use Jade cause as said that it's another fork for Waila like Hwyla is.
Even tho I've downloaded Waila in it's curseforge page but when loaded mc says Hwyla instead of Waila.
I don't download Hwyla itself anymore cause Waila nowadays is Hwyla, like as if it morphed/transformed itself into Hwyla entirely.

P.S. I've finally realized that Jade is basically Hwyla since jade was built around Hwyla and the reason why I'm still using Wawla/Hwyla is cause of the addon mod Wawla Harvestability.
Also Waila Harvestability works with Jade even tho I'll be testing to see if it actually does work and if it does work with Jade then I'll stop using Waila/Hwyla altogether for Jade which Jade is supposed to be better than both Wawla and Hwyla and even the original mod Waila.

Also It's Wawla not Waila that I'm currently using and was having problems with, was kinda confused with the naming since both of them have similar names, sorry for the confusion...
I know that what I've just said is irrelevant now cause of the change in the latest version of Advancement Plaques which was cause of me not knowing that you based the versioning off from Jade while I thought that Wawla's versioning was based off from Bookshelf which I'm clearly wrong since that versioning that is in the screenshot above is in fact from Hwyla which is an old version of Hwyla even tho there hasn't been any actual updates to it in quite some time now....
(Sorry for the "drama" btw)
