What is the highest lvl for totem?

I always thought it stop at 150, but with the changes happening in totem currently, I am not sure if it is a bug or the dev have increase the maximum level, I overclick the upgrading recently and I reached 151 on one of my totem. I dare not continue with my upgrading though I still have more than 3m exp points to use as can be seen in the ss. I need a confirmation before I proceed with my upgrading if now can upgrade to higher level.
