IndexError: bytearray index out of range

with half of scenario files
it happens when one of the secondary text blocks are JKR
It's gonna happen with 1_0_0_0_S1_T102_C0.bin by example.
But it won't happen on 1_0_0_0_S1_T10_C0.bin by example, which have only one text block.

Screenshot showing the presence of a JKR block still compressed

Used json file
scenario-1_0_0_0_S1_T102_C0.json
