I leveled my Traz last night 4 times on one world. I can level a building in that magic range multiple times in a single session, and some guild members harvest a huge number of prints. Then we give other guild members in need of prints the chance to get slots 4 and 5, which even at 1.9 would give a generous number of prints. I have a level 80+ Arc on a couple worlds, and the guilds I'm in there try to grow their buildings through the sweet spot zone by having other 80+ Arcs place 1.9 for slots 1-3. If a neighbor or friend or guild mate wants to lock in 1st on one of my buildings, I'm ahead already. It's FP I don't have to try to get, especially by trading some of mine. Other than detaching my GB from the town hall, I have no control over who donates to my buildings.

I prefer the principle that if you haven't locked a slot, it's not yours (yet). I can only advise that, going forward, your Guild come up with a policy on how to deal with this situation and what repercussions, if any, befall those who violate it if the Guild decides it should not be allowed. And, fortunately, few of my Guildmates give in to the temptation either, which makes for a good Guild as a whole. I'm not above being tempted to 'accidentally' donate 51 fp instead of 50, or 101 instead of 100 because the difference could be tens and tens of fp as a reward.but I don't give in. I can't tell you how often that I will see a GB in a swap thread with three or four players with the exact same amount of fp donated to it, the only difference being the one at the top made their donation before the others below. It sounds like this was an area of potential conflict not foreseen by your Guild, which, given the complexity of the game, is hardly surprising I don't think anyone can anticipate all possible situations and circumstances, rather only address them when they appear.
