[wix-users] Multiple msps in a burn bundle doesn't patch correctly

[Patterson, Brent]

Here's the situation:
We have a burn bundle that includes MspPackage for each MSP that the burn needs to run.  However, if there's more than 1 MSP file, for some reason some files doesn't get updated correctly or there's some kind of error.

For example:
0 to 1, then 1 to 2, then 2 to 3, it all works fine.
0 to 3, with MSPs for 1, 2, and 3 all listed in the burn bundle, it doesn't work correctly.  Most files gets patched, but some doesn't, and there's no errors.  Some cases, it even throws an error about some file not being found in the cab file.

Here's the planned packages part of log:
[6B00:68F8][2016-12-01T16:02:03]i201: Planned package: Patch1.msp, state: Absent, default requested: Present, ba requested: Present, execute: Install, rollback: Uninstall, cache: Yes, uncache: Yes, dependency: Register
[6B00:68F8][2016-12-01T16:02:03]i201: Planned package: Patch2.msp, state: Absent, default requested: Present, ba requested: Present, execute: Install, rollback: Uninstall, cache: Yes, uncache: Yes, dependency: Register
[6B00:68F8][2016-12-01T16:02:03]i201: Planned package: Patch3.msp, state: Absent, default requested: Present, ba requested: Present, execute: Install, rollback: Uninstall, cache: Yes, uncache: Yes, dependency: Register

Here's the applying part of log:
[8478:4CF4][2016-12-01T16:02:05]i306: Applying package: Patch1.msp, target: {945774F5-9F8E-46F7-9F91-FEDD93FE9B93}, action: Install, path: C:\ProgramData\Package Cache\{E5C600F2-F965-4130-BD18-724910E49FBA}\Patch1.msp;C:\ProgramData\Package Cache\{1E44C902-7D06-467D-B770-54BCA1A5B69B}\Patch2.msp;C:\ProgramData\Package Cache\{614389E9-C477-429F-AF01-39028B26D1B6}\Patch3.msp, arguments: '(null)'
[6B00:68F8][2016-12-01T16:02:13]i319: Applied execute package: Patch1.msp, result: 0x0, restart: None

The patches are sequential minor updates (i.e. 2 requires 1 to be installed before 2 can be installed).  If I run the bundle with only one msp at a time, it works fine.

This is what the chain element looks like in the patch bundle:

              <Chain>
                     <MspPackage SourceFile="{PATH_TO_PATCH_MSP}" Compressed="no" Cache="no" Vital="yes" />
              </Chain>

The MspPackage element is automatically added for each MSP by our internal build utility.  So if there's 3 MSPs, it would look like this:

              <Chain>
                     <MspPackage SourceFile="Patch1.msp" Compressed="no" Cache="no" Vital="yes" />
                     <MspPackage SourceFile="Patch2.msp" Compressed="no" Cache="no" Vital="yes" />
                     <MspPackage SourceFile="Patch3.msp" Compressed="no" Cache="no" Vital="yes" />
              </Chain>

Is there something that I'm doing wrong?  Is it slipstreaming or compressing or something when it shouldn't be?  Note that the MSP files are external, and not embedded into the burn bundle exe.
