I play with both bobores and angels refining (not bobplates) and got this while trying to see the ores
1639.861 Error MainLoop.cpp:853: Exception at tick 1458051: Error while running event MapLabels::on_gui_click (ID 1)
Unknown item name: angels-fissure

Thanks for the report. The bug is fixed in v0.15.3
