After having the release out for a few weeks, we're seeing some additional crashes on the Google Play console which are worrisome with BASS v2.4.17.0.

This one is our top crash.

Any ideas or suggestions?

The first crash looks like one that's fixed in the latest BASS build, which you can get here:

    www.un4seen.com/stuff/bass-android.zip

I haven't seen the second one before and unfortunately it isn't possible to tell the cause just from the call stack. If you're able to reproduce it, I can send you a debug BASSmix version to get more info. Otherwise, please try using this BASSmix update and see if it helps:
