In the recent versions, the multi-time reader fails to read all of the times on datafiles pv_%t.vtm, written with the ParaView XMLMultiBlockDataWriter. (Which pv_%t.vtm files are missing are repeatable for a fixed dataset, but vary with differing number of times and size of the datafiles.)
The multi-time reader successfully reads all of the times for datafile pv_%.vth written with the ParaView XMLHierarchicalBoxDataWriter.
In all previous versions going back to v3.98.1 these multi-time file types were both read in correctly. The bug appears to be present in the standard linux binaries at the ParaView download site, as well as in all of our local superbuilds.
Would it be possible to fix the bug prior to the v5.6.0 release?
