Crash when creating a blueprint of tiles

Hi, when trying to create a blueprint of only tiles (space platform foundation, concrete, brick, etc.) the game will crash with the following error:

================================================== The mod Rigor Module (0.1.3) caused a non-recoverable error. Please report this error to the mod author.

Error while running event rigor-module::on_player_setup_blueprint (ID 83) rigor-module/control-helpers.lua:400: bad argument #1 (closed) of 2 to 'pairs' (table expected, got nil) stack traceback: [C]: in function 'pairs' rigor-module/control-helpers.lua:400: in function <rigor-module/control-helpers.lua:394>

If there are other entities like assembly machines in the same blueprint, there is no crash however.
