Hi @mdouglass, Thank you for reporting the issue. Here is the DFJSON version of your model. Can you try to open this instead, and see if it works?

Hey @mostapha, still fails. Also, when I click “Load from folder” and select a different folder path for the Snapshots, I’m getting a “Duplicate snapshot failed” error. Not sure if this is related.

Hi @mdouglass, thanks! I can recreate the error after switching to V1. Give me a bit of time and I’ll send you the fixed version of the PoMF. This is a bug that was introduced in the latest version that I shared with you on Friday. I missed it because I don’t use the Model Editor V1 anymore. Sorry about that.

All good for now. Just finished manual modeling this one in VE :face_vomiting: I’ll keep an eye out for V2.

Hi @mdouglass,

I’m very sorry! That hurts. :frowning:

I wasn’t able to find a quick fix for this. The most reliable way to fix this is to switch back to an older version of the Revit plugin that you can download from Pollination. It will have the conflict with other add-ons but at least the Model Editor should work as expected once you disable the other add-ons.

I have already notified @mingbo and @antonellodinunzio about this issue. We should have a fix for it soon.

P.S. I wrote a longer paragraph here about switching to V2 instead, but I deleted it. I feel that will be a high risk proposal. Let’s wait a bit longer until we officially switch to V2.

I’ll probably reinstall 2.283.6.0 later this week. Any tips on troubleshooting the offending add-on? Just disable all and re-enable one by one? Thanks as always for the quick responses and solutions. It’s refreshing that you guys take such an active role in development and user feedback!

I see. In that case, we should have a new release for you with the fix. @mingbo is already working on the fix.

Yup. Unfortunately, there is not good solution to find the problematic one. Hopefully, you don’t have to do that though. We should be able to get you a fixed version by then.

Thank you! That’s the least we could do. :slight_smile:

A new version is ready to test. We will test it internally first and let you know when it is ready.

I think I’m having the same issue - can’t seem to load any snapshots. Where can I download the previous version to test that? I can only see the link to download the latest version. I’m working in Revit 2025.4.

Hi @mparkinson,

Try downloading the installer from the website. We have reverted it back to an older version of the installer.

Thank you for the quick fix, @mingbo!

I tested the new version with the fix, and the issue has been resolved. You can download the latest version (v2.284.6) from the website: Pollination

Sorry again about the issue. I did test everything in V1 this time to ensure they work as expected.
