Unsure at which point the error exactly happens. When I set a chest to pull stuff from storage, it seems to work, but then I get this error whenever I close the chest.
It's strange, because I got just one chest to pull from Storage, but any chest after that causes this error.

The mod Free market + bottomless storage (0.36.22) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event iFreeMarket::on_selected_entity_changed (ID 54)
LuaGuiElement API call when LuaGuiElement was invalid.

I can't sure that I fixed it even if it works for you, but I published new version to fix the issue:
https://mods.factorio.com/mod/iFreeMarket/downloads

Probably, I didn't fix it properly.

Another special update will be in several hours to find the bug and make it more stable.

So, another update should be stabler + I added new command "/fix-bugs", so you can figure out and fix much quicker. (update https://mods.factorio.com/mod/EasyAPI/downloads for the command)

I updated again, please use /fix-bugs to see if it has messages about desyncs.
