*Please help us to fix issues asap: to reduce checking with you back and forth, use the template below. Replace italic sections with your input.

For __support questions__, please use [stackoverflow with the [objectbox] tag](https://stackoverflow.com/questions/tagged/objectbox) - we get notified.*

- ObjectBox version (are using the latest version?): *?*

- Reproducibility: *[occurred once only | occasionally without visible pattern | always]*

*Describe the situation in English in which you encounter the bug.*

*Provide the code triggering the bug. Ideally, try to keep it short by removing as much code as possible while preserving the issue. You get __extra karma points__ for sharing a runnable project on GitHub that reproduces the bug.*

*Check if you have relevant logs and/or a stacktrace. For __build issues__, use `--stacktrace` for the Gradle build (`./gradlew build --stacktrace`). For __runtime errors__, check Android's Logcat (check also for relevant logs preceeding the issue itself).*

*Provide the code for entities related to the bug (shorten to relevant parts).*

*Is there anything special about your app? May transactions or multi-threading play a role? Did you find any workarounds to prevent the issue?*
