<div>I have fixed this bug. It did not come up in nightly tests because we are not using MatSetValuesLocal(). Instead we</div>
<div>use MatSetValuesClosure() which translates differently.</div>
<div><br>
</div>
<div>Here is the branch</div>

<div><br>
</div>
<div>and I have merged it to next. It will go to master in a day or two.</div>

Dear PETSc developers and users,<br>
<br>
Last week we posted a question regarding an error with DMPlex and multiple dofs and have not gotten any feedback yet. This is uncharted waters for us, since we have gotten used to an extremely fast feedback from the PETSc crew. So - with the chance of sounding
impatient and ungrateful - we would like to hear if anybody has any ideas that could point us in the right direction?<br>
</div>

</div>
<div>This is my fault. You have not gotten a response because everyone else was waiting for me, and I have been</div>
<div>slow because I just moved houses at the same time as term started here. Sorry about that.</div>
<div><br>
</div>
<div>The example ran for me and I saw your problem. The local-tp-global map is missing for some reason.</div>
<div>I am tracking it down now. It should be made by DMCreateMatrix(), so this is mysterious. I hope to have</div>
<div>this fixed by early next week.</div>
<div><br>
</div>
<div> Thanks,</div>
<div><br>
</div>
<div> Matt</div>
