Hi @Wuhucryoem
Thank you very much. I believe this is because the builder for the old job is out-of-date relative to changes made in v4.4.
To fix this, could you try building a new Volume Alignment Tools job from the builder (i.e. fresh from the job builder, without cloning the old one)? Then, could you connect the same volume/mask/particle inputs to this job and use the same parameters as before, and re-run the job? Then, I believe downstream particles should have location as well as all other slots retained.
