Wont start, simply throwing this error:

The mod Exotic Sea Block (0.4.11) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event exotic-seablock::on_chunk_generated (ID 12)
Unknown entity name: ei_2x2-container
stack traceback:
[C]: in function 'create_entity'
exotic-seablock/control.lua:99: in function <exotic-seablock/control.lua:23>

Will be fixed in next update.

Also found the issue in case some other people have it, the mod seems to require some of the optional submods of EI, this one came from the containers submod, just installed em all and now it booted fine.

Yes that one is require, no other mod is required, so should work now. Mod was updated
