May not be a normal issue, however, my 1.18.30 BDS had a script to allow chat ranks in it. Since the 1.19.0 update, the scripts no longer work, even after changing the manifest over to 'script' from 'javascript', it does not work. The rest of the behavior pack is still functioning as normal, but that aspect does not function at all anymore. However, it does still work in the Game Mode off of BDS.
