I believe this will cause infinite-loops, I strongly suggest you retest everything:

pawn Code:

isFaultyGameText("~r~")

Also, I don't think you need all that jazz. As long as the amount of tildes are even, the gametext or textdraw won't really cause bugs (even with wrong letters in-between). I'm simply using this code in my gamemode:

pawn Code:

stock isValidGameText(szText[]) {
    new
        iTildes
    ;
    for(new i = 0; szText[i] != EOS; ++i) {
        if(szText[i] == '~') {
            iTildes++;
        }
    }
    return !(iTildes & 0b1);
}
