Many bugs when active both ruleset and initial map in custom game

Screenshot with unintended behaviors (Image(s) Here):

If you can reproduce it, write the steps here. If you can't, try to describe the exactly time the game crash, like pressing which key or which button (Details Here):

1. Import this custom game setting: Techmino Quest:1OZbag!g!!eJwTEgICRiEYoBsLAM8vB6U=!
2. Set ruleset to dig_10l
3. Clear all the bone blocks
4. -2 lines remaining

Solution [pseudocode]:

if linesRemaining <= 0 then
    set linesRemaining to 0
    call win function
end

actually many custom rulesets have conflicts with initial sequence/field things, this will be impossible after "More Powerful Custom Update"
