This is not a bug.
You are getting this message because the crystal symbol you have chosen has no simulation model associated with it.
From V4.1.1, the location of simulatable components has changed. Apart from a few passive parts (R, L, C and a few transformer symbols) they are no longer in the EasyEDA Libs.
You can now find them by doing **SHIFT+F** or **More Libraries...** then looking under:
`System Components > Spice Simulation`
You will find Crystal under:
`Spice Miscellaneous`
This pulls in the XTALFast model which has user editable parameters in the right hand panel.
