Yup, just get SE. Mods need to be updated to work with the Anniversary Edition, and a lot of authors haven’t done that yet. You’ll need to downgrade SE, but there’s an easy tool to do just that.
If you wanted to buy Special Edition for Steam, GMG (key seller with great reputation) has it on sale for roughly US$9.
Happy to see Meta booted from the industry, but I’m a bit concerned about Google no longer indexing news articles here…
