I've spoken with several authors and seen others note on the Nexus that they're holding off on updating and/or converting their mods until SKSE64 reaches its "final" version. The authors of YASH (Yet Another Skyrim Hardcore mod) and Requiem are just two examples that come to my mind, as I'm interested in those mods. Unfortunately, as noted by the redditor in the recent Reddit topic I linked above, this is exactly the opposite of what the SKSE64 team was expecting by releasing the SKSE64 alpha - they were hoping modders would help test it so it could then safely move to beta and final versions. However, hopefully Ian now sees this as he indicated in the Reddit topic and will move forward to beta soon so things can finally normalize. As Ian notes, there's only one known bug with the alpha in any case (the autosave issue described earlier), and it already has all functionality that will be included in the final version. Fingers crossed.
