MapServer error: la theine plateau 'rainbow' is nil value

[SirGouki]

I have:

• searched existing issues (http://github.com/darkstarproject/darkstar/issues/) to see if the issue I am posting has already been addressed or opened by another contributor
• checked the commit log to see if my issue has been resolved since my server was last updated

Client Version (type /ver in game) : 30191227_0

Source Branch (master/stable) : master

Additional Information (Steps to reproduce/Expected behavior) :
GameServer log: [Error] luautils::OnTOTDChange: scripts/zones/La_Theine_Plateau/Zone.lua:90 attempt to index local 'rainbow'(a nil value) keeps popping up
Checking the appropriate lua files (zone.lua and the ID.lua) shows that rainbow is set to an id, by default, but this error is still happening.

in IDs.lua
RAINBOW = 17195606,

in Zone.lua
 elseif (I_Can_Hear_a_Rainbow == 1 and TOTD < dsp.time.DAWN or TOTD > dsp.time.EVENING and rainbow:getAnimation() == dsp.anim.OPEN_DOOR) then
    rainbow:setAnimation(dsp.anim.CLOSE_DOOR);
