First of all, thanks for the work on this mod. For a long time I was searching for an offline game similar to Wurm and thanks to you I finally found it.
It seems that the greenhouse script was broken in previous version and current 9-22-14 version seem to be also affected. When you close the door it doesn't reset the "cropsfroze" event, at least if you have more than one greenhouse. Effectively, the crops freeze even if you close the greenhouse. I believe, that changing:
[\mods\Massive Mod\sys\objects_buildings.inf:4043]: freetimers 0,"cropsfroze";
(located in on:use event/else statement of greenhouse, line 4003 in earlier version) to:
freetimers "self","cropsfroze";fixes this issue. From what I understand the old freetimers 0 should reset event on all existing greenhouses (objects?) leading to another bug, but for some reason resets none.
Keep up the good work,
OgiX
