A lot of the users of DW20 seem to be getting crashes similar to this with various machines.

Modlist for DW20 1.0.14 : https://feedthebeast.atlassian.net/wiki/display/PML/Direwolf20+%281.6.x%29+1.0.14

I am guessing this is a cross mod error but I am unable to pin down where the problem is.

@AEnterprise So it was an invtweak mod bug ?

known bug, already fixed

for the users with the problem: replace the region files with region files from a backup, otherwise try to find the corrupt file and delete it

What do I need to update in the packs to resolve this?

I don't see anything in the recent commit logs that could have fixed this on lp's side.

I don't think that that is even an LP bug. Looks more like InvTweaks is not checking the size of the Container.

So something I need to talk to InvTweaks about then?

Yup, looks like it. :)

@davboecki i had the same thing heapen to me several times until i updated LP, not sure about the version that fixed it but it doesn't heapen anymore for me
