You could put an ERA version check in your mods. It's just a matter of a few minutes. I do it for my mod too.
In that statement, you can explicitly tell people to use a certain ERA version because the mod was developed and tested for that version. Together with that, you put a link where they can download that version.
That should reduce the number of complaints and give us time to fix either ERA or your mods so they work with the newest version if you want that.
