JMC thinks `[-1]` is a string slice

[WingedSeal]

summon::entity.Pos = summon::objectives[-1].Pos;

raises

Unexpected token (Token(token_type=<TokenType.KEYWORD: 'Keyword'>, line=175, col=56, string='.Pos', _macro_length=0, quote='')) at line 175 col 56.

This is actually caused by a misalignment of merging path tokens (AKA. I just missed a +1 but that took half an hr to find).
Should be fixed in 0393bed
