resource annotation update caused crash

In a running interactive session consider a node witht he following %hist:

READY  2024-11-06T09:32:22+01:00 prop_pd27h14 = Property energy ((structure: geom_Pd27H14), (calculator: calc)) on 36 cores for 2.0 [hours]

Updating the resource annotations in the following way:

Input > prop_pd27h14 := Property energy ((structure: geom_Pd27H14), (calculator: calc)) on 72 cores for 5.0 [hours]

Leads to the following error message and session crash:
