I am losing my shit trying to figure this one out. I though my config wasn't working, but read in another post that the plugin has issues.

Anyways you can get this working again @rfc1920. 

The building decays for me, but not the external wall and they are not in TC area either I want the walls to decay within 3 minutes.

Should I set the Decay.tick to 180 instead of 600 or does the plugin modify that value to represent what our multiplier is set to ?

Seems to me like the 

Line 312 doesn't have the right entity name

else if (entity_name == "wall.external.high.wooden")

I think Facepunch might of change the entity to 

else if (entity_name == "wall.external.high")

I was wanting to speed up the decay. I was thinking that

wood 3 hours

stone 5 hours

sheet 8 Hours 

HQM 12 Hours

i wanted for it to decay faster 

If I wanted everything to decay within 2 Hours I would devide it by half the number right?

So a multiplication of 6 for HQM 12/2

4 For Sheet 8/2

2.5 for Stone 5/2

1.5 or wood 3/2 

Twig I left alone

But nothing was working :(

Now I use this plugin https://umod.org/plugins/custom-decay

But it has no maintainer :(
