Hair type particles from curve objects with bevel depth, they disappear on particle object.
Make Object with particle->hair type->render as: object->instance object: make and select any curve object.
In curve object->Curve tab->Geometry->Bevel->Round->Depth->if you set more than 0 particles will disappear, also same issue with extrude and bevel modifier.
