    I couldn't find anything online about this error:

    Archive file was modified while it was opened, and can no longer be accessed: [Bundle Path]


    does it happen if we overwrite to a loaded texture or something?

    I'm not familiar with cases where this can appear, but from looking at the code I can see that this error would be logged if a AssetBundle file (e.g. Unity Archive file format) is detected to have a changed modified time during the process of loading. Is it possible the file is being written to, for example in the process of downloading, and is being opened too soon?

    Hi, I think this was caused by calling AssetBundle.LoadFromFile for the same path multiple times somewhere in our code. We've updated the code to properly cache the opened bundles.

    Same mistake. I don't know how it was caused.
