@Aelvi You should get the ascension-specific version from the addons discord: https://discord.gg/xM4cf8XS4s
If there are no ascension-specific version of the addons you need, either in that discord or in the launcher, you should always use 3.3.5a versions of generic addons, since that's the client version ascension runs. 3.3.0 could also work if there is no newer available.
