Group Pose Not Working With Doze Consistently

Date & Time: October 12, 2017
Frequency: Always
World name: Excalibur, but all worlds affected.
Character name: Shima Kyaro, but applies to all characters.
Retainer name: N/A
NPC name: N/A
Monster name: N/A
Class/Level: N/A
Party or solo: N/A
In-game time: N/A
Area and coordinates: N/A
Housing: N/A
Steps:
1. /doze on a sleep-able surface
2. /gpose
3. If you used /gpose immediately after, as your character is laying down, the command will work. If you use /gpose after your character has fully laid down, it will not.

For some further explanation, I tested this in multiple locations in-game, both inside of and outside of a personal home, and had the same result each time. If I used /gpose instantly after executing the /doze command the /gpose would function as normal.

After my character had settled into her animation however the /gpose would no longer work. The same is true if you exit /gpose after successfully doing it and try to use it again. Additionally, trying to /cpose while laying down and using /gpose immediately after also disables your ability to /gpose. I tried doing these as fast as I could but the result is the same each time.

The bug report I'd previously posted was moved from Accepted Bugs to Duplicate Bugs, and I didn't see any other bug reports about this in any of the other bug sub-forums, and as of the time of this posting this is the first thread in In-Game bugs, so I'm not sure where the duplicate is.

Either way, more testing today revealed more information so hopefully this new report can help isolate the issue. I hope this is enough information!
