hi, i have done a lot work on appendages in recent update, mainly updating the source code and such. i don't fully understand the request. do you mean the appendage automatically swaying/ wagging?
for the V1.4 issues, yes.. this version had so many issues due to getting very paranoid and uploading it early, i am currently taking my time more with V1.4.1, since there was issues with the tracking methods ^^
i will see what i can do
