There's a new beta out! FirmWeave 2.6rc1 is now available for testing and general use.  Only a couple changes here vs 2.5:

Bugs Fixed:

• Some CFG element definitions (like .cycle) did not read negative numbers.
  • This is important because OopPlaceTile (used in #PUT and #CHANGE) reads the cycle from ElementDefs when deciding whether to attach a stat to an element.
  • So if you want to use sharks or centipede segments as decorative elements and don't want to eat up your stat limit, you can define them with a negative cycle in your .CFG file.
  • This change will make its way to SoftWeave as well.

Added:

• Added Object counters 6-10 with a range of 127 to -128.
  • You have a reasonable expectation for these values to be 0 when an object is created in a modern editor; however, it's best to explicitly set these before using them to make sure.
    • A warning about the above ^ will be added to the .INI files and to the FIRMDEMO.
