What is the max level for the fireplace in the workshop in the Abandoned Camp?

I’m at level 136 fireplace. It cost 945k to upgrade and my workshop time is down to 3.4 seconds

I'm at 148 and not there yet

I'm at lvl 131. Cost is 725k time 3.6 seconds

TLDR:

It'll take over 400 days of leaving your phone on 5+ hours a day to complete this. I'm contacting the devs to see if they can drop the max-level of the workshop to level 100.

Long version:

I'm at level 118, but I have recorded totals back to level 108. From 109 to 113, the increase in wood-cost was the previous day + X. From 109 to 110, X=12k. Level 111, X=13k, level 112, x=14k. By level 114, X was increasing 1k every level.

Even if the equation remains X=X+1k for every successive level, the total wood needed just from level 118 to level 250 is 607,278k or 607.278m.

I've been leaving my phone on for 5 hours a day just to collect wood (since I accidentally completed all the tasks and moved onto the next level, killing the ability to idle on Abandoned Camp). I'm currently only earning about 4-5 levels at a day, and I'm not even at level 120.

I'm contacting the devs to see if they can change the max-level for the Workshop to 100.

My fireplace is at level 146. It cost 1.61M to upgrade and the time is down to 3.1 seconds. I will continue to update this post till I get it maxed out.

I’m at 52 and still not maxed out..
