good to hear your internet issue has been fixed.
let's just say kazmuth & i are VERY much familiar with UP/Teacher's village area (up to Sikatuna)
it is for instances like this that we need to keep the maps locked to a certain level.
new aspiring editors are thereby constrained to seek assistance from the waze editing community.
this gives opportunity for the senior editors to explain why certain things in the map are set to the way they are.
unlike our google maps & other navigation aiding maps where crowd sourced info is also applied, waze map editing is very unique. as we always need to consider navigation/routing (for driving wazers) on top of other aspects like aesthetic presentation.
previously (last year), waze told us to enable the U-Turns (green).
then recently, as stated by kazmuth, waze has instructed editors globally to keep the U-Turns 'red' in compliance with a recent change in the routing algorithm.
only in special instances that the U-Turns need to be enabled nowadays.
best if we could brush up & dig through the wiki guides to keep you up to speed on the editing conventions.
on the matter of the routing quirks, waze introduces changes in the routing calculations recently and as a result, has been affecting several wazer's routing. we've even seen an instance where waze sent a wazer going in circles
just bear with the ongoing changes & tinkering of our servers for now.
