I have created four pics to illustrate what I was trying to accomplish. Step 1 - Everything is working fine Step 2 - Where I am selecting previously saved character actions, in this case I want him to get down on all fours to look under table. Step 3 - Shows the script cutting off exactly at the point where the custom action is inserted. Noted that this step cuts into and overwrites a segment of existing motions. Step 4 - Shows where I broke the one motion and deleted several poses to make room for the custom motion, same result. I hope this helps in your efforts to uncover the reason for this.
IMPORTANT: This may very well be something I did, as it only happens when I used the two actions to go down or go up. Does not do this for the other two custom actions; Fred Standing, or Looking around
