"Remove Racial Restrictions for Single Classes" fails to install on default TobEx

[the bigg]

As per topic title; I'm reporting the error, although I find it strange that it hasn't been reported yet...

 

relevant debug.log:

relevant code:

  FOR (col = 2; col < 9 ; ++col) BEGIN
    SET_2DA_ENTRY 0 col 9 1
  END

  BUT_ONLY

relevant mgsrcreq.2da (notice it has 1 title + 7 data = 8 columns, vs. the 9 referenced in the code):

Relevant version information: I'm using BG2 + TOB "classic" (not BG2EE), bg2_tweaks v16, tobex v26; --change-log reports no other file touching mgsrcreq.2da.

 

The component "open all kits to all races" assumes 9 columns as well, but performs a COUNT_2DA_ROWS before patching, resulting in no error being raised and the file not being changed by SET_2DA_ENTRY (it is changed by PRETTY_PRINT_2DA).
