[BUG] PatchyBonds Observable Causes Crash

[JeDeveloper]

Describe the bug
When I try to run the DetailedPatchySwapInteraction in contrib/rovigatti with the attached files, the following occurs

To Reproduce
Steps to reproduce the behavior:
Unzip the attached files in a folder.
Edit input file to update plugin_search_path to your local oxDNA/contrib/rovigatti
Run in terminal oxDNA input
if the line observables_file = observables.json is removed from the input file, oxDNA runs as expected.

Expected behavior
DetailedPatchySwapInteraction and PatchyBonds observable should function as expected.
I have previously run simulations with the same observables.json file so the problem is clearly the combination of the observable and this specific conf.
The starting conf rapidly explodes when I ran the simulation without observables.json, however an explodey conf should not cause a free(): invalid pointer error.

Desktop (please complete the following information):

• OS: Ubuntu
• oxDNA Version: latest version, commit 6052b17
• cmake version 3.16.3
• Make 4.2.1
• g++ 9.4.0

Everything works fine on my box. Maybe you git pulld and recompiled the code but not the plugins?

Any news on this one?
