can't seem to auto download mods

[Zavindur]

this happened around the time the new client with the ice adapter thing was implemented; was never a problem before (that I can recall).

sometimes I join a game and it makes no attempt to download the mods, when i get in the lobby i get kicked for not having the mods;
I check the mod vault; sometimes I will already have the mod installed and sometimes I won't;
I'll install the mod thru the mod vault.
When I try to join the game again - sometimes it will say i'm still missing the mod I had just downloaded (sometimes it won't complain and I can play).

What is the proper procedure with the new downlords client to get mods to auto-install when joining games and what are some things I can do to fix this?

(I have deleted my mods folder/reinstalled client/tried legacy client)

i cleared the log files then tried to join a game that had mods; I then uploaded the attached logs.
