Premium Package Data Usage Bug

1 min read - Published: 4 hours ago

Hello, everyone. We have identified a bug which was introduced in our September 9th release, which unfortunately caused premium packages to use excessive data usage after installing/updating. We have released a hotfix today which fixes this issue.

If you were forced to buy extra data storage due to this bug and do not wish to keep the extra storage, please contact us at [email protected] to get a refund.

If you have been affected by this bug, please follow these steps to fix your data usage:

  • Go to https://forge-vtt.com/setup and open "Data Storage".
  • Check in the "Others" tab, sort by size. If there are any large .zip files, delete them.
  • Check the systems and modules tabs as well. Sort by size. If there are any which are larger than 50 MB:
    - Delete them
    - Go to https://forge-vtt.com/bazaar
    - Find and reinstall the affected package(s)

We deeply apologize for all of the inconvenience this has caused to our users. We have implemented changes to our QA and deployment procedures to avoid issues like this in the future.

If you don't care about the technical details, you can stop reading here. Happy gaming, everyone!

The Technical Bits

For the technically interested, we can share a few more details. Forge uses two types of storage - Data and Assets - to optimize both performance for users and hosting costs. Due to how Foundry handles premium modules, the entirety of the module must first be installed in a user's Data storage. It is rather undesirable to store large media files there (thus the whole reason for the split between the two storage types), so after the premium installation we run an optimization step which moves all of the media to the user's Assets Library.

As of the 9th, module installations started to skip the optimization step. This left all of the module's images, audio, etc... in Data, often leaving users in excess of their data quota. Being over data quota prevents launching games on Forge, so this had an unfortunately large impact on users.
