It seems that the changes from version 1.19 to 1.20 brought this movement bug while the hippogriff is flying.

Same issue here, even without other mods installed. My current Ice & Fire is version 2.1.13-1.20.1+build.beta-4 and Citadel is 2.5.4.
This is easily tested by spawning in a few hippogriffs and waiting for them to take off. They do eventually come down, but it's quite rare, and their time on the ground is usually too brief to tame them.
