Has any thought been given to hosting this pack some place like GitHub? It would make it much easier for individuals to make updates to small numbers of files. For instance, I have changes to the signs and fish so that they are correct in 1.14, but I'm not sure how to upload then or get them merged in with the changes that others are making. Approval of changes through GitHub could be handled with pull requests, and git would manage the merges and conflicts.
If you upload a zip of the files to google drive and send me a share link, i can add them to the main pack.
I've added some of the new files to the main pack and will be uploading it shortly, adding it to the OP as a BETA WIP pack
EDIT: FYI the chest fix I added that's at the top of the change log is not melonthrids update. Its the one i updated ages ago to fix the clipping and added the red eyes for the trapped chests. For whatever reason it wasn't in the latest version.
