[0.9.13] Kotlin app build fails with ToOne relation

My app bild fails whenever I add ToOne relation to my class with following error

* What went wrong:
Execution failed for task ':mdd_tester:transformClassesWithObjectBoxAndroidTransformForResearchDebug'.
> Could not transform entity class "com.rbot.mdd.tester.chat.Message" (cannot find com.stfalcon.chatkit.commons.models.IUser)

What strange is that IUser class that it seems to not be able to find is not the target relation of ToOne class and is just a filed in my entity class that I use with PropertyConverter. Here is the fields of my entity class:

    @Id var id: Long = 0
    @Convert(converter = UserConverter::class, dbType = String::class)
    lateinit var user: IUser
    @Transient
    var report: Report? = null                         // Manual relation
        get() = if (reportId > 0) DataManager.reportBox[reportId] else null
        set(value) = value?.let {
            field = it
            field?.persist()
            reportId = it.reportId
        } ?: Unit
//    lateinit var report2: ToOne<Report>    Build fails if this line is not commented
    var reportId = -1L
    var text = ""
    var image = byteArrayOf()
    var date = Date(now)

Yes, that was expected. Will have a .15 shortly…
