Addons download freezes when joining world

When joining friends world with a bunch of mods (what I've noticed, above 20MB) the mods downloading just freezes and Im unable to join the frind or the game even crashes in rare situations.

 

A temporary fix to download my friends addons so I could join him is my friend create a world and add one addon one by one so I can download them one by one.

 

This should be fixed asap since addons are so popular and with people using a bunch of them, getting obligated to do this temporary fix is so boring that people prefer to play something else than doing all the this...
