[Users] TwoPunctures warning message

Hello,

I am running TwoPunctures for the first time and I see warnings like:

WARNING level 1 in thorn Carpet processor 3 host node032.damiana.admin (line 393 of /home/baiotti/Cactus/arrangements/Carpet/Carpet/src/Storage.cc): -> There are not enough time levels for the desired temporal prolongation order in the grid function group "TWOPUNCTURES::PUNCTURE_U". With Carpet::prolongation_order_time=2, you need at least 3 time levels.

Since TwoPunctures is run only at initial data, prolongation should not be necessary. Could those variables be tagged as prolongation-none?

Cheers, Luca
