The only calls to rcn_ref before are:
rcn_ref=01 {set rcn_ref=1 }
rcn_ref=02 {set rcn_ref=2 }
rcn_ref=03 {set rcn_ref=3 }
rcn_ref=04 {set rcn_ref=4 }
rcn_ref=05 {set rcn_ref=5 }
rcn_ref=06 {set rcn_ref=6 }
rcn_ref=07 {set rcn_ref=7 }
rcn_ref=08 {set rcn_ref=8 }
rcn_ref=09 {set rcn_ref=9 }
set rcn_ref='${rcn_ref|subst:^0+~>}'

So basically as I wasn't sure if it will work, I thought let's catch all 
double 00 with this command. If I comment out the last line, then the 
map compiles just fine without any error messages.
