    I filed a new bug of this issue for iOS platform, likely the cause is same.

    Hello Unity People. The issue is not fixed. It is still reproduceable in the latest beta, that is Unity 2018.1.0b9. Please look into this. If it will not be fixed and this will be still reported as fixed I will create a new BUG report similar to this one.

    I can confirm that this is not fixed in 2017.3.1p2 even though it says it was fixed in 2017.3.1p1. Tested in WebGL.

    I have the same issue for iOS builds, which I have tested on the iPhone SE.
    Mac, Windows and Android Builds (Sony Z3, HTC M9) are fine.

    Same thing is happening to me. Why does this say it's fixed, when it's clearly not fixed?

    This was listed as fixed in build 2017.3.1p1 but I can also confirm that the issue described still persists (at least on iOS). Code stripping issue seems to be fixed though. Priority for fixing this should be elevated as it pretty much renders the whole tilemap unusable on iOS.

    Stacktrace I get when setting tiles via Tilemap.SetTile()

    Error running RefreshTile for previous TileNullReferenceException: A null value was found where an object instance was required.

    When will this get fixed? I am still having the issue in 2017.3.1f1.

    It says fixed in future release but it does not say which one. I checked release notes for all 2017.3 patches (patch 4 is most current) and did not see it so fix does not seem available yet.

    I am still experiencing this problem on the most up to date Unity version with WebGL builds. Anyone else still having problems?

    This issue also appears on 2017.3.0 and 2017.2.1in WebGL builds (In Windows Standalone everything works fine). The tile doesn't just "not appear".
    SetTile throws an error: "NullReferenceException: A null (value was found where an object instance was required.) "
