Tie Flame level to higest altar level

Suggestion : have a single upgrade path in the altar to avoid confusion between upgrading the altar and upgrading the flame.

Maybe a niche issue but I just spent 30 hours of gameplay "stuck" at flame level 3, a bit of a stupid mistake but it could happen to someone else. I had stopped playing for a while and came back to kill the shroud wyvern in the pike, made a trophy out of it, and got confused that I couldn't get through the deadly shroud blocking the way to the nomad highlands. I ended up in a catch 22 where I thought I needed to upgrade the altar to get shroud adhesive, but needed shroud adhesive for the altar upgrade. Only when I googled requirements to get through deadly shroud did I finally realise my mistake....

Mostly my own doing, I guess if there was a clearer distinction between the two it wouldn't have happened. I'm not entirely oblivious (I hope) but I could see this percieved obstacle being the end of someone's run in enshrouded and that'd be a shame.
