DCS_Export_Script causes low GPU and CPU utilisation on complex missions

[JS312RAF]

Hello.
I've noticed that on one MP mission (Fortress Europe by Reflected), my GPU and CPU utilisations went very low (40% & 10%), resulting in low FPS.
Troubleshooting revealed DCS_Export_Script (v1.2.1) is the culprit, or rather deleting it from Scrips folder solved the issue.
Please advise.

Still an issue for me sadly. Tried doing a fresh DCS and DCS Export Script install.
