rain bug? Biomes.

[Sarakatunga]

Hello 7-day people, I have a problem with the rain, it happens that on the dedicated server it never rains it just clouds the sky, but when I play a game only on my pc with the same biomes.xml, works!, I already had this problem in alpha 17.4, now it happens The same in alpha 18. What am I doing wrong?

Biomes.xml Alpha 18 B143:

<!-- Pine Forest Main Biome -->

<biome name="pine_forest" topsoil_block="terrForestGround" biomemapcolor="#004000">
