Modelsim vsim-3033 error can't find instantiation is the -L handle broken?

[wtr]

The following is the dump

vsim -L work test.sd_cmd_master_tb
# vsim -L work test.sd_cmd_master_tb
# Start time: 16:38:27 on Jan 03,2018
# Loading sv_std.std
# Loading test.sd_cmd_master_tb
# ** Error: (vsim-3033) ../../../bench/verilog/sd_cmd_master_tb.sv(72): Instantiation of 'sd_cmd_master' failed. The design unit was not found.
# Time: 0 ps Iteration: 0 Instance: /sd_cmd_master_tb File: ../../../bench/verilog/sd_cmd_master_tb.sv

Notice that it doesn't look in the work library but rather the test library twice.

to put into context the following works

vmap diff_name work
vsim -L diff_name test.sd_cmd_master_tb
# vsim -L diff_name -L test test.sd_cmd_master_tb
# Start time: 16:46:34 on Jan 03,2018

I never use -L with the work library it's modelsim's default library and I've noticed it has a different behavior than libraries that are vmap'd (and therefore show up in the modelsim.ini file. There is an existing forum member that is employed by Mentor that can probably explain this in more detail.
