Filesize limit in multiplayer?

[TeganJovanka]

I've been playing multiplayer with my son on his server (we're not on the same LAN). Everything has worked well until a few days ago. Now I get dropped from his server as soon as the map is loaded.

Steps:
1. The map downloads.
2. My computer loads the map.
3. I get dropped.

The map we were playing reached 20MB a couple days ago, that's when I started getting dropped.
We tried starting a new game and there was no problem.

Has anyone else seen this?
Any suggestions?

the one who hosts the game should go into the save zip and remove "replay.dat", which removes the filesize by 40-60%, as it's just the replay file, used if you want to watch a replay of what you did on your run, which i doubt many people have used so far.

Afaik there is no limit on the file size. Sounds like you two are experiencing a desync right when you load that drops you from the game. Try loading one of your earlier autosaves. If you still desync at ~20mb then i expect you have a bad connection between you two that times out once in a while,which is only noticable when downloading larger files. If you are not on 0.12.20 then update to that version of factorio as it's the newest version.
