Lua Constant loop while loading otserv lua modules libs?

[feverdog]

Hello, there is something that has always bugged me and I really hope someone can help me with it.

On TFS 0.3.7 (I don't know if this happens to any other) when I put a script to execute something in the module lib like on: data/talkactions/lib/example.lua or in data/lib/0023-example.lua it just keep looping over and over again.

if you try to execute like this on example.lua:

do
    local executed = false
    if not executed then
        print('hi')
        executed = true
    end
end

It keeps looping print function, just like with any other thing that I try to execute in module_name/lib (actions, talkactions, etc) or in data/lib/filename.lua

Notes: the spells/lib/ seems safe from loop calling, but the others are just messed up.

Doesn't this affect performance at server startup?
Is there any catch that I do not know with it? Can someone help me solve this please?

Thanks in advance.
