Hello!
Sometimes "Disassembled" tab contains an error.
For example, here is random one of the recently uploaded contracts: https://verifier.ton.org/EQDuB7okS4POUbDiKewK9Kkmu2fIrvg8vgW3uvsCeN6hIB4a
And the error in this case is:
Error: Index 80 > 80 is out of bounds
Seems like the disassembler engine is too old and can be replaced with new one @tact-lang/opcode. This fixes the problem.
Possible fix is #427
