Is it possible to stop the indent of comments after a certain amount for Expressive?

I found this for Flexible Squares but it doesn't seem to work for me. It works until I add #4 to my theme layer and then I always get errors. Since I have clue what compiling errors mean I'm helpless.

Error compiling layer:

Compile error: line 1330, column 41: Unknown property S2::NodeVarRef, S2/NodeVarRef.pm, 171 S2::NodeVarRef, S2/NodeVarRef.pm, 151 S2::NodeTerm, S2/NodeTerm.pm, 174 S2::NodeTerm, S2/NodeTerm.pm, 66 S2::NodeSum, S2/NodeSum.pm, 65 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeSum, S2/NodeSum.pm, 64 S2::NodeTerm, S2/NodeTerm.pm, 76 S2::NodeTerm, S2/NodeTerm.pm, 66 S2::NodeExpr, S2/NodeExpr.pm, 46 S2::NodePrintStmt, S2/NodePrintStmt.pm, 55 S2::NodeStmtBlock, S2/NodeStmtBlock.pm, 108 S2::NodeFunction, S2/NodeFunction.pm, 230 S2::Checker, S2/Checker.pm, 374 S2::Compiler, S2/Compiler.pm, 34
