Hi, I seem to get an non-recoverable error upon picking up a blueprint. I don't have a large base in 2.0 yet to test if it's entities from there, but for me I can create new blueprints just fine. It seems to only happen with blueprints created before 2.0, error message provided below:

The mod Cargo Ships (1.0.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event cargo-ships::on_player_cursor_stack_changed (ID 32)
LuaItemStack API call when LuaItemStack was invalid for read.
stack traceback:
[C]: in function 'get_blueprint_entities'

cargo-ships/control.lua:339: in function <cargo-ships/control.lua:337>

I also get this

Same error here too, attempted to import Nilaus' starter base and got this error.

Should be fixed in the latest update, 1.0.5

Seems to still be present in version 1.0.6 https://prnt.sc/wy6OwXBC2MZ8

That's a different error. Any way you can share the save or blueprint?

Here you go, but it only happens on a multiplayer server, not in singleplayer:

Oh that must be it, I haven't tested any mods in multiplayer yet. I just pushed an update that I think will fix it (checking is_blueprint_preview in the right places).

cheers, will test tomorrow or so and then report back

Seems to be fixed, thank you!
