Lumb roar interrupts grooming process

Hello everyone,

ive noticed, as stated in the title, that the "roar" which Lumbs do from time to time interrupts the grooming process for its duration. After the roar is finished, the groomer picks up where he was interrupted, and finishes the groom. I couldnt confirm if the dupe in question starts doing other tasks while the Lump is "untargetable", or just always waits it out. In the cases ive seen, he waited till the critter was done.
I decided to report this, since im not sure if its intended to be this way.

Cheers.
